Melanomas of female genital tract are rare tumors with poor prognosis. While BRAF-V600E is the most common pathogenic mutation seen in cutaneous sun-exposed melanomas, mucosal and anogenital melanomas usually lack BRAF mutations and instead they harbor KIT alterations. The American Joint Committee on Cancer staging guideline (AJCC eighth edition) recommends using cutaneous melanoma guidelines for vulvar melanoma staging and does not provide any recommendations for vaginal melanoma staging. The aim of this study is to investigate the mutational status of invasive melanomas arising from different anatomic sites in lower female genital tract (vulvar hair-bearing skin, glabrous skin, vagina and urethra) in a group of 37 patients. Tumors were analyzed using a DNA targeted next-generation sequencing panel covering the 21 most common genes and mutation hotspots in melanomas. The most common genetic alterations in invasive melanomas of lower female genital tract are KIT (32%), TP53 (22%), and NF1 (19%). Overall 66% (21/32) of cases showed a pathogenic alteration in at least one of the MAPK pathway genes. No statistical significance seen between different primary tumor sites and the frequency of the oncogenic mutations, nor were any significant differences found by mutation status. Only one case of urethral melanoma showed a BRAF non-V600E mutation (D594G). Our results suggest a similar molecular pathogenesis and overall survival in melanomas arising from lower female genital tract, irrespective of their exact location in the urogenital area. Future classifications of melanoma should consider grouping vulvar melanomas with mucosal rather than cutaneous melanomas.

Background Malignant melanoma of the lower genital tract is a rare disease known to have a poor prognosis. Because of the high rate of distant metastasis and unsatisfactory survival benefit, a more conservative treatment approach, instead of extensive surgery, may be warranted. Gynecological melanoma is a radioresistant tumor, an ideal disease to test the biological efficacy of carbon ion radiotherapy (CIRT). Aim To report our preliminary experience with CIRT in the treatment of gynecological melanoma at the National Center of Oncological Hadrontherapy (CNAO). Patients and methods Between January 2016 and February 2017, four patients were admitted for CIRT at CNAO. A case of cervical melanoma was treated with palliative aim because of large volume macroscopic disease, while three cases of vaginal melanoma were irradiated with a total dose of 68.8 Gy (relative biological effectiveness) in 16 fractions delivered over 4 weeks (4 days a week). Results The age of women ranged between 49 and 72 (median=60.5 years) years. Treatment was well tolerated in all patients and all women completed the scheduled treatment course. During CIRT, toxicity was mild. For patients with vaginal disease, local control was 10.23 and 12.6 months, while that for cervical malignant melanoma was 7.3 months. All patients experienced systemic progression, with median distant metastasis-free survival of 11.7 months. The median overall survival for the whole patient group was 11.41 months. Conclusion In our first experiences, CIRT appears to be a safe non-invasive option for malignant melanoma of the lower genital tract, but more data and longer follow-up are necessary in order to evaluate the effectiveness and late effects.

Vaginal mucosa represents a rare site for primary melanoma. These neoplasms more commonly occur in the postmenopausal period, usually presenting with vaginal discharge, bleeding, or palpable mass. We report a case of an 89-year-old woman presenting with vaginal bleeding and a non-pigmented lesion in the lower third of the vagina at the gynaecological examination. A PAP smear and tissue incisional biopsy were concurrently performed. The cytological sample showed a subpopulation of non-cohesive, atypical epithelioid cells suggestive for malignancy. The histological examination showed the same morphological characteristics in the neoplastic population widely underlying the vaginal epithelium, with scattered intraepithelial nests and single elements. In both samples, there was no evidence of melanin pigment within the malignant cells. Immunohistochemical analysis performed on the tissue biopsy demonstrated a strong and diffuse positivity for melanocytic markers (HMB-45, S-100, Melan-A), confirming the diagnosis of primary amelanotic vaginal melanoma.

Introduction Vulvar and vaginal melanomas are rare cancers of the female genital tract and account for 1% to 3% of all melanomas diagnosed in women. Due to the rarity of the disease, few data are available on the clinical and pathologic features of these cancers. Furthermore, treatment options are generally based on extrapolations of the information available for the more common cutaneous counterparts. Surgery represents the mainstay of treatment for lower genital tract melanoma. Moreover, the role of sentinel lymph node (SLN) assessment is controversial because no prospective data are available. Evidence acquisition Data were collected from MEDLINE, EMBASE, Web of Sciences and Scopus databases. On July 10, 2020, we used the search comprising the terms "vulvar melanoma", "genital melanoma" and "vulvovaginal melanoma" including only studies in which SLN biopsy was performed. Evidence synthesis Ten retrospective studies have been found. No randomized trials have been reported. The studies included 132 patients while only 63 (47%) undergone SLN. 99mTC with or without blue dye followed by ultrastaging was highly accurate and is currently the gold standard. Mean detection rate was 98.3%. No clear evidence supported the execution of back lymphadenectomy (after SLN mapping), in fact, extrapolating data from cutaneous melanomas of other sites, completion of lymphadenectomy does not confer a melanoma-specific survival advantage. Conclusions Although the small amount of available data, sentinel lymph node procedure is feasible and capable of identifying patients who have occult lymph node metastases. However, the potential role of the sentinel lymph node procedure as an alternative method of lymph node staging in patients with vulvar or vaginal melanoma needs further investigation.

Primary vaginal melanoma is a rare mucosal neoplasm, which is more aggressive than cutaneous melanoma. Information regarding its morphologic patterns is limited. In particular, the rhabdoid phenotype, mostly observed in metastatic or recurrent cutaneous melanomas, has yet to be reported at this anatomic location. Hence, a potential diagnostic difficulty may arise because of the inability to recognize this unusual histologic variant and its immunohistochemical aberrance. In this report, we describe the case of a primary vaginal melanoma in a 62-year-old woman, who exhibited both rhabdoid and small blue round cell morphologies, absence of S100 protein, and aberrant expression of desmin, CD56, and FLI-1. This report can facilitate the task of expanding the morphologic spectrum of vaginal melanoma, and prevent misdiagnosis and inadequate medical treatment.

Malignant melanoma of the vagina is a rare, aggressive malignancy of poor prognosis. It principally affects post-menopausal women, with a mean age of 57 years, and the factors that contribute to its appearance are not well known. The first case of primary malignant vaginal melanoma was reported in 1887 and modern literature has noted about 500 cases, globally. Vaginal melanomas constitute 0.3% of all malignant melanomas and fewer than 3% of all vaginal carcinomas. To date there is no clear consensus regarding treatment. An early, accurate diagnosis and prompt investigation is essential in reaching appropriate treatment decisions. We present a clinical case of primary vaginal melanoma and review the literature briefly, presenting the current treatment plans and updates of this rare gynecological malignancy. Considerations, epidemiology, associated risk factors, response to therapy and expected outcome are also discussed. Conclusion: Primary malignant vaginal melanoma is a rare but aggressive melanoma that affects women in their 6th and 7th decade of life. The tumor appears as a dark node or spindle but can also be amelanotic. The size of the tumor is indicative of the prognostic factors. Surgery seems to be the only efficient treatment. Postoperative adjuvant therapy might help in preventing recurrence of the tumor. The survival rate is largely dependent on nodal and distant metastasis of the disease after initial tumor resection. There is a dire need to form a proper therapeutic regime to control this disease.

Genital melanoma is a rare pathology. We present the experience of two comprehensive cancer centers in Lyon (France) in the management of genital melanoma in order to identify prognostic factors and optimal treatments. Between April 1992 and Mars 2014, 16 patients with a primary genital melanoma were referred to our department. Nine patients presented a vaginal melanoma, six vulvar melanomas and only one cervical melanoma. The median dimension of the lesion was 33.7 mm (5–100 mm). The AJCC stage ranged from IB to IIIC. 12 cases were the classic dark-blue flat melanoma and the other 4 cases were an atypical amelanotic tumor. Wide local surgery was performed in nine patients. A radical surgery was performed in six patients. In the large cervical melanoma, radiotherapy was performed as first-line treatment. In all the patients regional lymph node staging was performed. Adjuvant treatment was realized in nine patients. Two patients are alive without recurrence. Only one patient was lost to the first follow-up. The other 13 patients experienced a rapid recurrence. The median disease-free survival and the median overall survival were 11.8 months (2–49 m) and of 30.4 m (11–144 m), respectively. The disease-free survival and overall survival could be linked to a clinical presentation (Breslow thickness and morphology of lesion) associated to the early diagnosis. In our small series, the most important prognosis factor remains the tumor thickness. These rare lesions should be treated in experienced centers in order to improve their prognostic.

Objectives The aim of this work was to determine molecular characteristics and specifically, the frequency of BRAF, C-KIT, and NRAS mutations in vulvar and vaginal melanomas. Methods A retrospective review of all cases of vulvar and vaginal melanoma between 2002 and 2013 was performed. We reviewed the clinical and histological characteristics of all cases and performed genotyping studies on cases that had tissue available for the study, using next-generation sequencing. Results We identified 33 vulvar and 11 vaginal melanomas in women with mean ages 58 and 61 years, respectively. Next-generation sequencing analysis on 20 cases (15 vulvar and 5 vaginal) identified a BRAF mutation in 7.6%, C-KIT mutation in 27.6%, NRAS mutation in 27.6%, and TP53 mutation in 7.6% of the vulvar cases. We detected only a single TP53 mutation in the vaginal cases. We did not identify any statistically significant relationship between the mutation status and patients' outcome, depth of invasion, ulceration, stage at presentation, or lymph node metastasis. Conclusions BRAF mutations are infrequent, whereas C-KIT and NRAS mutations are seen with higher frequency in vulvar melanomas than melanomas of other sites. These mutations can be considered as potential therapeutic targets in patients harboring them. Further studies are necessary to increase our understanding of mutational events occurring in melanoma of the lower female genital tract and their relationship with clinical parameters/outcome.

We report the case of a 70-year-old woman with vaginal melanoma and multiple metastases in the lung. After the third dose of nivolumab, decreased room-air resting arterial oxygen saturation with bilateral basal fine crackles on auscultation developed despite the absence of respiratory symptoms. Computed tomography showed ground-glass opacities with airspace consolidations scattered with a peculiar distribution, and most were observed around the existing metastatic tumors in the lung. From the 42nd day to the 56th day after the last administration of nivolumab, she received dexamethasone 1-2 mg/body for the prevention of adverse events after stereotactic radiation for brain metastasis. At 3 months after the last administration of nivolumab, a computed tomography scan revealed improvement of the pneumonia and a decreased size and number of metastatic lesions in the lung, although some lesions showed enlargement. Further examination is needed to clarify the relationship between the pattern of pneumonia after Nivo therapy and clinical effects.

Objective To describe the characteristics of primary vaginal melanoma patients in the Surveillance, Epidemiology, and End Result database and to determine the outcome from the treatment approaches. Materials/Methods From the Surveillance, Epidemiology, and End Result registry, 201 patients with vaginal melanoma were identified. Patients’ characteristics and prognostic factors including age, race, extent of surgery, and use of radiation therapy were obtained. Results The median age was 68 years (range, 28–100 years). The population was 73% white, 11% black, and 16% Asian/American Indian. International Federation of Gynecology and Obstetrics staging results were stage I (46%), stage II (18%), stage III (3%), stage IVA (3%), stage IVB (12%), and unknown (18%). Treatment approach included surgical resection of the primary site in 70%, whereas 35% of the patients underwent lymph node resection. Approximately 40% of the patients received radiotherapy, which was primarily used in the adjuvant setting. Overall survival at 2 and 5 years was 24% and 15%, respectively. Presence of lymph nodes at diagnosis was associated with worse overall survival (hazard ratio, 1.98; P = 0.02). Adjuvant radiation did not offer a statistically significant overall survival advantage compared to surgery alone. Conclusions Vaginal melanoma is a rare diagnosis primarily affecting the elderly. Overall survival is low even for patients presenting with disease limited to the vagina. Lymph node involvement at diagnosis is strongly predictive of worse overall survival. Most patients are treated with surgical resection with varying use of adjuvant radiotherapy. Further research is needed to identify the etiology and improve the outcome of this aggressive disease.

We aimed to compare the differences in demographic features, clinicopathologic features, and survival in patients with vulvar/vaginal melanoma versus cutaneous melanoma with a special emphasis on race.Data were obtained from the Surveillance Epidemiology and End Results database from 1973 to 2008. Kaplan-Meier curves and Cox multivariate model were used for statistical analysis.Seven hundred sixty-two patients with vulvar/vaginal melanoma and 55,485 patients with cutaneous melanoma patients were included in the study. Twenty-eight patients of the vulvar/vaginal group and 334 patients of the cutaneous group were black (3.6% vs 0.6%, respectively). The median age at the time of diagnosis was 68 years in the vulvar/vaginal group and 52 years in the cutaneous group (P0.0001). Three hundred fifty patients (45.9%) in the vulvar/vaginal and 46,499 patients (83.8%) in the cutaneous group presented with localized disease (P0.0001), whereas 64 patients (8.4%) in the vulvar/vaginal group and 1520 patients (2.7%) in cutaneous group presented with advanced disease (P = 0.0081). The median survival of the black patients was 16 months in the vulvar/vaginal group and 124 months in the cutaneous melanoma group (P0.0001). The median survival in the nonblack population was 39 months in the vulvar/vaginal group compared to 319 months in the cutaneous melanoma group (P0.0001). In multivariate analysis performed for patients between 1988 and 2008, age, stage, and positive lymph nodes were negative independent prognostic factors for survival in vulvar/vaginal melanoma; whereas age, race, stage, radiation therapy, and lymph node positivity were negative prognostic factors in cutaneous melanoma.These findings emphasize that cutaneous and vulvar/vaginal melanomas have different clinicopathologic features and survival patterns.

Objective We report our experience with vulvar (Vu) and vaginal (Va) melanoma, with review of surgical and adjuvant therapy guidelines and description of our use of neoadjuvant therapy in selected cases. Methods We reviewed patients seen at Mayo Clinic for management of Vu or Va melanoma, January 1993–February 2012. Surgical treatment, pathologic and outcome data were abstracted. Overall survival (OS) and recurrence-free survival (RFS) were estimated using the Kaplan–Meier method, and compared between subgroups using the log-rank test. Results 50 patients underwent surgery for primary or recurrent melanoma (Vu=36, Va=14). The 5-year OS rate was 30.9%, with median OS of 3.3years. Adjuvant therapy was given to 30.6% of Vu cases with varying combinations of agents. Among Vu patients, after adjusting for node status and depth of invasion, adjuvant therapy was not associated with improved OS (p=0.39) or RFS (p=0.31). Preoperative chemotherapy was used in 2 Va cases. Despite temozolomide followed by exenteration for a 4cm multi-focal lesion, one patient died within 3months. The second patient, with a 2cm vaginal lesion, demonstrated a partial response to carboplatin and paclitaxel (CP). After local excision and lymphadenectomy she received additional CP with bevacizumab and remains disease free at 5years. CP with bevacizumab was also used in 1 Vu case with a solitary 5cm midline lesion. She underwent vulvectomy after a partial response, received additional CP and bevacizumab postoperatively, and remains without disease at 2years. Conclusion Preoperative chemotherapy with CP and bevacizumab may improve treatment outcomes, particularly for Va and large Vu lesions.

Purpose: Mucosal melanoma is a rare but aggressive subtype of melanoma with unique clinicopathologic features. We hypothesize that mucosal melanoma shows predilection for separate and unique metastatic pathways. Materials and methods: This was a retrospective analysis of 19 patients (5 men and 14 women; median age 60 years, range 38–76 years) with metastatic mucosal melanoma presenting to a tertiary oncology center between 2005 and 2010. We performed a review of medical records and histologic and imaging studies to evaluate the natural history, metastatic patterns and the role of imaging in the management of patients with advanced mucosal melanoma. Results: At presentation, disease was confined to the primary site (58%, n = 11) or to the regional lymph nodes (32%, n = 6) in most patients. The most common site of metastasis was the lungs (89%, n = 16), followed by the liver (67%, n = 12) and peritoneum (44%, n = 8). Sinonasal melanoma preferentially spread to the liver (100%, n = 4), vaginal melanoma to the lungs (100%, n = 7) and anal melanoma to the inguinal lymph nodes (100%, n = 4). Conclusion: Pathways of metastatic spread in mucosal melanoma may differ from other forms of melanoma and between different primary sites of mucosal origin.

Objective The aim of the study was to evaluate the surgical management and the role of different prognostic factors on survival outcomes of women affected by genital (i.e., vulvar and vaginal) melanoma. Materials and methods Data of patients undergoing primary surgical treatment for genital melanoma were evaluated in this retrospective study. Baseline, pathological, and postoperative variables were tested to identify prognostic factors. Five-year disease-free survival (DFS) and overall survival (OS) were analyzed using Kaplan-Meier and Cox proportional hazards models. Results Overall, 98 patients met the inclusion criteria. Sixty-seven (68%) and 31 (32%) patients in this study population were diagnosed with vulvar and vaginal melanoma, respectively. Median (range) DFS and OS were 12 (1-70) and 22 (1-70) months, respectively. Considering factors influencing DFS, we observed that at multivariate analysis, only vaginal localization (hazard ratio [HR] = 3.72; 95% CI = 1.05-13.2) and number of mitoses (HR = 1.24; 95% CI = 1.11-1.39) proved to be associated with worse DFS. Nodal status was the only independent factor influencing 5-year OS in patients with vulvar (HR = 1.76; 95% CI = 1.22-2.54; p = .002) and vaginal (HR = 3.65; 95% CI = 1.08-12.3; p = .03) melanoma. Conclusions Genital melanomas are characterized by a poor prognosis. Number of mitoses and lymph node status are the main factors influencing survival. Surgery is the mainstay of treatment. A correct and prompt diagnosis is paramount.

To evaluate the carcinogenic potential of implanted synthetic mesh midurethral slings in the treatment of female stress urinary incontinence. We identified female patients undergoing implantation of mesh materials for stress urinary incontinence at our institution from 1 January 2002 to 31 December 2012. This was accomplished by querying the medical records for CPT code 57288 (“sling operation for stress incontinence”) and a subsequent chart review to identify patients who underwent synthetic mesh sling placement. Medical records were then evaluated for the documentation of bladder, urethral, vaginal, cervical, uterine or ovarian cancers via the International Classification of Disease (ninth edition) coding. A chart review of patients with a cancer diagnosis was performed for verification of the diagnosis and evaluation of the temporal relationship with sling placement. During the study period, 2,474 patients underwent polypropylene midurethral sling placement. The median age was 57 years (IQR 47, 69) and the median follow-up was 60 months (IQR 23.3, 94.9). Overall, 51 patients also had a cancer diagnosis (8 bladder cancers, 7 vaginal malignancies, 8 ovarian carcinomas, 26 endometrial cancers, 2 cervical malignancies); however, only 2 cancers (0.08 %, 2 out of 2,474) developed following sling placement (a vaginal melanoma 3 years after sling placement and an ovarian tumor 1 year after sling placement). No cases of sarcoma formation, bladder, urethral or squamous cell carcinomas were identified. With a median follow-up of 5 years after synthetic midurethral sling placement, development of pelvic malignancy was rare (0.08 %) and unlikely to be secondary to foreign body reaction from the implanted material.

We report two cases of malignant melanoma metastasizing to the ileum and jejunum in a 48-year-old female and 62-year-old male, respectively. The female patient was a known case of vaginal melanoma who on follow-up developed pain abdomen 4 years after excision of the primary, whereas the male patient who was initially referred as pleomorphic spindle cell sarcoma of the groin presented with complaints of bleeding per rectum and melena 6 years later. After preliminary investigations both underwent laparotomy and resection of segments of ileum and jejunum with tumor. Histopathological examination with immunohistochemistry showed features suggestive of metastatic malignant melanoma. Metastasis should be suspected in patients with malignant melanoma who develop gastrointestinal symptoms such as abdominal pain, anemia, melena, fatigue, constipation, small bowel obstruction, or perforation. This helps in avoiding a delay in the diagnosis and complications that arise due to metastatic disease. Our first patient with primary vaginal melanoma died of multiple metastases 11 months following surgery for the ileal metastasis while the second patient with jejunal metastasis developed recurrent disease in the small bowel and iliac lymph nodes 10 months after surgery. However, in a patient with isolated gastrointestinal metastasis, diagnosed early, with good general condition surgical management should be encouraged when a complete resection of the disease is feasible as no other treatment option is as good for relief of symptoms and prolongation of life.

Background Primary vaginal melanoma is a rare, highly malignant, and poor prognostic disease. Case The 51-year-old patient with diagnosis of vaginal malignant melanoma was referred to our clinic. Since detection of pervasive brown lesions in the vagina total vaginectomy was performed. At pathological investigation melanoma was not determined. Immunotherapy was administered adjuvantly. Paraaortic lymph node metastasis was seen on the ninth month after total vaginectomy and the metastatic lymph nodes were excised. Cisplatin and tremozolamide chemotherapy was administered for six cycles after surgery. The patient is alive and disease-free at 18th month of the diagnosis of the disease. Conclusion The impact of therapy on outcome of primary vaginal malign melanomas is poorly understood. Improved clinical outcomes were associated with surgical removal of gross disease whenever possible. Because of the low rate of lymph node metastasis, elective pelvic lymph node dissection is not mandatory. We presented a case of FIGO stage I primary vaginal malignant melanoma, which metastasized to the paraaortic lymph nodes 9 months after the primary

Malignant melanoma is a tumor of melanocytic origin. Lymphatic and hematogenous metastases are common in this condition. Retrospective analysis was performed in 16 consecutive cases diagnosed histopathologically as malignant melanoma at the pathology department of a medial college in eastern India. 75% of the patients were male; majority of them was in their sixth decade. All (100%) the lesions were pigmented. The primary site was known in all cases, except two (12.5%). Out of the 14 cases with known primary site 11 (78.57%) were cutaneous melanomas, including one arising in labia minora, two (14.29%) were ocular and one (7.14%) was vaginal in origin. Among cutaneous melanomas, superficial spreading type was the commonest variety and mixed population of epithelioid and spindle cell was the commonest histopathological pattern. The commonest grade of invasion was grade III (Clark′s). The clinical presentation of the case of vaginal melanoma and the two cases of secondary melanomas, including the one with obscure primary tumor, were bewildering and hence are discussed separately.

Primary melanoma of the urogenital tract in women is rare, but biologically aggressive. They usually affect elderly women and account for less than 10% of all cancer of the urogenital tract in women and less than 10% of all melanoma diagnosed in women. Tumours originate from melanocytes that are present in the urogenital mucosal epithelium of about 3% of women. Tumour staging can be challenging; however, the American Joint Committee on Cancer melanoma staging system has been recommended for use in vulvar and vaginal melanoma. Surgery is the treatment of choice; less-extensive surgery can be a sensible approach because satisfactory locoregional control might be obtained from wide local excision and radiotherapy, without the morbidity and disfigurement associated with radical surgery. Complete regional lymphadenectomy does not seem necessary if a sentinel lymph-node biopsy sample is negative; however, this decision should be made with caution. Various chemotherapy and biotherapy (ie, immunotherapy and biological-response modifiers) regimens have been used in advanced or metastatic melanoma. However, the role of chemotherapy for women with urogenital-tract melanoma has not been established, and biotherapy methods presented to date have been anecdotal.

Background Mucosal melanoma of the female genital tract that recurs locally after definitive surgery presents difficult challenges for salvage therapy. Methods and Materials A 71-year-old female was diagnosed with a 4.5-cm × 4.1-cm × 2.8-cm vaginal recurrence of genital tract mucosal melanoma after definitive vulvectomy, distal vaginectomy, and distal urethrectomy. She refused surgery and underwent combination external beam radiation therapy (46 Gy) and an ultrasound-guided palladium-103 brachytherapy implant (100 Gy). Results The patient experienced complete resolution of the gross tumor and was asymptomatic with a sustained response for over a year before developing metastatic disease. Conclusions Mucosal melanoma of the female genital tract is an aggressive and often fatal disease. Radical surgical excision is an option for some patients but may require pelvic exenteration and is rarely curative. In selected cases, high-dose conformal radiation therapy delivered by a combination of external beam radiation therapy and interstitial brachytherapy may be an excellent alternative, achieving local control without loss of organ function.

The authors of this article present a case of a woman diagnosed with a vaginal melanoma who developed paraneoplastic syndrome (PNS) soon after diagnosis. A review of the literature regarding PNSs in gynecological malignancies is also described in this article. To our knowledge, this is the first reported case of paraneoplastic cerebellar degeneration with opsoclonus myoclonus secondary to a vaginal melanoma. In addition, our patient had an unusually acute progression to pancerebellar symptoms over the course of 3 weeks. Her paraneoplastic symptoms improved significantly after partial resection of the melanoma.

Vulvovaginal melanomas are rare and their etiology is unknown. Genital mucosal human papillomavirus (HPV) 16 has been identified in both cutaneous and mucosal melanoma, suggesting that it might play a role in the pathogenesis or progression of melanoma. In this study, we investigated the prevalence of HPV DNA by using a broad spectrum of degenerate and type-specific primers for genital-mucosal, epidermodysplasia verruciformis-associated (EV), and cutaneous HPV types in 6 vulvar and 3 vaginal melanomas. The patients were mostly postmenopausal women (8/9), had a mean age of 67 years (range, 44-85 years), and had mucosal lentiginous (7) or nodular (2) melanomas. In the adjacent skin/mucosa, mucosal melanosis was found in 5, lichen sclerosus or a lichenoid mucositis in 4, and blue nevi in 2 women. With nested polymerase chain reaction techniques followed by direct sequencing, HPV DNA was identified in 6 of 9 (67%) melanomas; these were either cutaneous (HPV 3) (4/9) or epidermodysplasia verruciformis-associated types (HPV 38, Z95969, AJ00151) (4/9). Epidermodysplasia verruciformis-associated HPV (type 15) was found solely in 1/10 (10%) normal vulvar controls. Genital-mucosal HPV types were not detected either by degenerate nested polymerase chain reaction or type-specific probes for HPV 16. We propose that the above findings are not coincidental but may represent a molecular record of HPV involvement in pathogenesis or progression of melanoma, which is consistent with the strong but poorly defined association of cutaneous HPV types with nonmelanoma skin cancers. The theory that HPV may act as a cofactor in melanoma development deserves further clinical and experimental investigations.

Background Primary genitourinary (GU) melanoma is a rare disease, which is poorly characterized. Objective To examine clinical characteristics and survival outcomes of primary GU melanoma among men and women. Design, setting, and participants Retrospective study using the Surveillance, Epidemiology, and End Results database (1973–2010) was used to identify primary GU melanoma cases by tumor site and histology codes. We examined associations of GU melanoma with demographic, clinical, and pathologic characteristics, as well as disease-specific survival (DSS). Outcome measurements and statistical analysis DSS was calculated using the Kaplan-Meier method. Cox-proportional hazard models were used to calculate hazard ratios and 95% CI for factors associated with worse DSS. Results and limitations A total of 1,586 histologically confirmed cases of primary GU melanoma were identified with a median age of 66.1 years (IQR: 55–80). Incidence of primary GU melanoma was 0.2 cases/million among men and 1.80 cases/million among women. Overall, 60.1% of patients had localized disease at presentation and 90.5% of patients had cancer-directed surgery. Patients with urothelial melanoma had the worst 5- and 10-year DSS (39% and 29%, respectively). Women with vulvar/vaginal melanoma had worse 5- and 10-year DSS compared to men with penile/scrotal melanoma. In multivariate analysis, decreased survival was associated with increasing age, distant stage, and lymph node involvement. Results are limited by the lack of standardized staging for primary GU melanoma and the retrospective design of our study. Conclusions Patients with primary GU melanoma present with advanced stage and have a poor prognosis. Women have worse DSS compared to men. DSS is negatively associated with advanced age at diagnosis, higher stage, and lymph node involvement. Patient summary Clinicians and patients must be aware of the poor disease-specific outcomes associated with primary GU melanoma. Most importantly, women fare worse than men and mucosal melanomas have worse outcomes compared to cutaneous melanomas.

Objectives. Only few population-based incidence analyses of vulvar melanoma including the United States and Sweden are currently available. We studied the incidence of vulvar melanoma in a large population-based cancer registry of East Germany and compared our findings with the United States and Sweden. Methods. We extracted vulvar melanoma registered between 1976 and 1989 in the former National Cancer Registry of the German Democratic Republic (GDR) and of three new East German cancer registries of the federal states of Sachsen, Brandenburg, and Mecklenburg-Vorpommern of the period 1998 to 2002. We calculated age-specific and age-standardized incidence rates using the World Standard Population. Results. One hundred two cases (1976–1989, former GDR) and twenty-five cases of vulvar melanoma (1998–2002, three new federal states) were registered. The age-standardized incidence rate (World Standard Population) remained constant over the period from 1976 to 1989 and ranged between 0.26 and 0.52 cases per million. From 1998 to 2002, the incidence rate was 0.48 per million. The ratio of registered vulvar melanoma to skin melanoma was 1:71, and the ratio of vaginal melanoma to skin melanoma was 1:314. Age at diagnosis during the period 1976 to 1989 was lower among women with vulvar melanoma (median age 70 years) compared to women with vulvar tumors other than melanoma (median age 73 years). Conclusions. The risk of vulvar melanoma was considerably lower in East Germany than in the United States and Sweden. Due to the rarity of vulvar melanoma, population-based cancer registries are hampered to study this tumor in detail.

Objective. This is a retrospective analysis of malignant melanoma of the female genital tract, focusing on the high local recurrence rate of this tumor. Methods. All women treated for malignant melanoma of the genital tract were identified through the archives of the Hadassah University Hospital. The medical records and the pathological specimens were reviewed and reevaluated. Results. From 1986 to 2002, nine cases were diagnosed and treated at Hadassah. Seven had vulvar melanoma and two had vaginal melanoma. Sixty-six percent (6/9) of the patients had more than one focus of melanoma, either apparent at their initial diagnosis (3/9) or developed during follow up (3/9). Most of the recurring lesions were melanoma in situ. In one patient multiple nodular melanomas were detected. Atypical melanocytic hyperplasia was found in an otherwise normal mucosa in four patients. Three had experienced multiple recurrences. All patients were treated by radical local excisions with (3/9) or without (6/9) elective groin lymph node dissection. Three patients with locally recurring melanoma within the genital tract required two to five sessions of repeated surgical excisions. Conclusion. It is suggested that melanoma of the genital tract is the result of a multifocal disorder of the melanocytes within the mucosa. The increased local recurrence rate reflects an inherent abnormality of melanocytes. It is not attributed to surgical failure in controlling the disease. Insistent and even radical surgical excision is recommended, especially for patients whose prospects for prolonged survival are improved.

Background Urogenital melanoma is a rare neoplasm with poor prognosis. Its management in the past involved radical vulvectomy and complete bilateral inguinofemoral lymphadenectomy. Sentinel lymph node biopsy is an accurate low-morbidity procedure when used in the context of cutaneous melanoma. However, prophylactic lymphadenectomy has not been shown to improve survival of melanoma patients. We wanted to determine the feasibility of sentinel lymph node biopsy in patients with female urogenital melanoma as a staging procedure. Methods Six patients with vulvar or vaginal melanomas underwent preoperative lymphatic mapping with (99m)Tc-labeled sulfur colloid followed by sentinel lymphadenectomy. In addition, we reviewed the literature on the application of sentinel lymph node biopsy in urogenital tract melanomas. Results One or more sentinel nodes were identified in all six patients by lymphoscintigraphy. All patients underwent sentinel lymphadenectomy, except for one patient with a deep vaginal melanoma that drained to pelvic nodes. The five successful cases had unilateral drainage patterns. None of the sentinel lymph nodes excised had tumor invasion. Combined with five other patients from the published literature, the success rate of localizing sentinel lymph nodes in the patients with urogenital melanoma approaches 100%. Conclusions This experience, plus reports of a small number of patients from three similar studies, supports the impression that sentinel lymph node biopsy is feasible for vulvar and vaginal melanoma.

Results All nine samples showed positive staining for HMB-45. Five cases showed intensive staining, two moderate and two weak. The positive staining was black in the cytoplasm of melanoma cells but was detected in neither the background nor normal squamous cells. Though destaining of Papanicolaou stain was not performed before immunostaining, the positivity of immunostaining was easily judged. Conclusion After morphologic observation, immunocytochemical study of HMB-45 is possible even though time has passed since the cytologic specimen was obtained. When there is a suspicion of amelanotic melanoma or scantily pigmented melanoma of the vagina and vulva, cytogenesis with HMB-45 is helpful, especially because it involves little invasion.

Primary vaginal melanoma is a rare malignant tumor. We review the clinical presentation and magnetic resonance imaging (MRI) appearances of this entity in four patients. The MRI findings in vaginal melanoma are various and may be confused with other malignant vaginal tumor. Pelvic MRI is helpful for accurate preoperative staging of vaginal melanoma.

Objective The aim of this study was to evaluate a series of primary melanomas of the female urogenital tract for oncogenic mutations in KIT , NRAS and BRAF in order to identify patients who may be amenable to targeted therapy. Methods We reviewed twenty-four cases of female urogenital tract melanomas and used Sanger sequencing analysis for the detection of oncogenic mutations in exons 9, 11, 13, and 17 of KIT ; exons 2 and 3 of NRAS ; and exon 15 of BRAF . Results Twenty-four patients were included: fourteen vaginal melanomas, four cervical melanomas, five urethral melanomas and one vulvar melanoma. NRAS mutations (4/24, 21%) were more prevalent than KIT mutations (1/24, 4%), while BRAF mutations were absent. Three of four NRAS mutations were present in vaginal melanomas (21%), mainly affecting codon 61 (3/4). They were mutually exclusive with the KIT mutation. The KIT mutation was present in a vaginal melanoma and affected exon 17. Conclusions Melanomas of the female urogenital tract relatively commonly harbor mutations in NRAS ; this makes NRAS an interesting therapeutic target for these patients in the advanced setting. KIT mutations were rare in our study in contrast to some previous reports. We cannot exclude that anatomical site-related differences and/or population related differences in KIT mutation frequency exist within urogenital tract melanomas.

Vulvovaginal melanomas are rare tumors that account for a small fraction of all vulvovaginal cancers. Biologically, they seem to be similar to mucosal and acral melanomas of other sites. There are limited data specific to vulvovaginal melanomas, especially regarding systemic therapies. Most treatment decisions are based on extrapolation from data regarding cutaneous melanomas of other sites. It is reasonable to follow already established guidelines from other professional groups and societies. Outcomes tend to be worse compared with cutaneous melanomas likely because of the later presentation and physical biological characteristics of these tumors.

ObjectiveThis study aimed to identify prognostic factors of survival and improve treatment strategies in women diagnosed with primary malignant melanoma of the vagina.MethodsBetween December 2002 and August 2011, 44 patients with lesions confined to the vagina and diagnosed with melanoma at Fudan University Shanghai Cancer Center were evaluated retrospectively. Prognostic factors were analyzed by Kaplan-Meier method.ResultsWith a median follow-up time of 18.9 months (range, 6.0–94.3 months), 30 (68.2%) patients developed recurrences, whereas 21 (47.7%) died of disease. Median progression-free survival (PFS) was 14.4 months and median overall survival (OS) was 39.5 months. Depth of invasion (DOI) was significantly associated with OS (P = 0.023), and there was an obvious tendency toward improved OS with a negative lymph node status (P = 0.063). The DOI was significantly associated with lymph node status (P = 0.047). The extent of surgery (wide local excision vs radical excision) was not associated with differences in PFS or OS (P = 0.573 and P = 0.842, respectively). Longer PFS was observed in patients who received adjuvant chemotherapy and radiotherapy (P = 0.038).ConclusionsThe prognosis of primary vaginal melanoma is dependent on the DOI and lymph node status in our study. Surgical resection of disease, especially wide local excision, should be considered as the optimal treatment when complete removal of tumor with a negative margin is possible. Adjuvant therapy may be associated with a longer PFS.

Aims: To document the clinical, morphological and immunohistochemical features of two cases of primary mucosal melanoma with osteocartilaginous differentiation. Materials and methods Two cases of mucosal melanoma with cartilage and bone formation are reported, one arising in the vagina of a 79-year-old woman and one in the oral cavity of a 67-year-old man. The vaginal melanoma exhibited only cartilaginous differentiation. The oral cavity mucosal melanoma exhibited both bone and cartilage formation and was remarkable for its multifocality, long history not associated with metastases and its lengthy manifestation of dual morphologies: some of the tumours were typical in situ/invasive melanotic melanomas whilst the others were composed of amelanotic spindle and epithelioid cells with osteocartilaginous tissue. One of the lesions exhibited in situ and invasive melanoma with transition to an osteogenic tumour in places. The patient also developed non-osteogenic malignant melanomas in the nasal cavity and nasopharynx. Conclusions Malignant melanomas showing foci of osteocartilaginous differentiation are extremely rare with only 18 cases reported. Primary mucosal malignant melanomas of vagina and oral cavity showing osteocartilaginous differentiation have not previously been documented. Primary vaginal melanoma with cartilaginous differentiation must be distinguished from primary malignant mixed Mullerian tumour whilst malignant change in a pleomorphic adenoma, sarcomatoid carcinoma, osteogenic sarcoma and mesenchymal chondrosarcoma are included in the differential diagnosis of primary oral mucosal melanomas with osteocartilaginous differentiation. In this context, immunohistochemistry using antibodies to cytokeratin, S100 protein and MIC2 is of value.

We present a case report of a woman who has survived 13 years after conservative treatment with wide excision for vaginal melanoma and review and evaluate the literature on this disease since the last metaanalysis in 1989.A database literature search along with cross referencing from related articles uncovered 66 patients who were reported to have vaginal melanoma since 1989 with adequate information for our analysis. We add to this one original case reported by us. Where information was available, we analyzed outcomes on these cases on the basis of patient age, tumor thickness, tumor size, and treatment.The patient we describe is only the eighteenth reported patient to survive vaginal melanoma 5 years and only the third to survive for 10 years. Of the 67 patients in our overall review, mean age at the time of diagnosis was 62 years. Patients with tumor size3 cm had a mean survival of 41 months compared with 12 months for those with tumor sizeor = 3 cm (p0.0024). Tumor thickness did not significantly affect patient survival at any of the depths analyzed, although there was a tendency toward significance at depths8 mm (p0.0778). There also was no significant difference in patient outcome among five treatment groups: (1) wide excision, (2) radical surgery, (3) radiation therapy, (4) wide excision plus radiation therapy, and (5) other.Tumor size appears to affect survival in patients with vaginal melanoma. Tumor thickness, at least at the levels at which vaginal melanomas are currently being diagnosed, does not seem to affect survival. Because no single treatment is clearly preferable, we suggest conservative resection where possible. We find it difficult to support radical surgery as primary treatment for vaginal melanoma unless necessary to achieve clear tumor margins. Radiation therapy appears to offer results comparable to those of surgery.

The outcome of patients presenting with vaginal melanoma has been assessed in a large multicentric retrospective study. The databases of 12 French institutions were searched for primary vaginal melanomas managed between 1990 and 2007. Among the 54 patients recorded, 46 were managed with a curative intent and included in the study. The clinical characteristics, treatments, and detection of c-KIT protein expression have been studied. The median age of the patients was 63.5 years (42-88). Twenty-eight patients were classified as International Federation of Gynecology and Obstetrics (FIGO) stage I, five as stage II, six as stage III, and one as stage IVA. c-KIT protein was overexpressed in 80% of the patients. Forty-two patients underwent surgical resection of the tumor, nine patients received local adjuvant treatment, and 10 received systemic adjuvant therapy. The median relapse-free survival was 10.9 months. c-KIT-negative status (P=0.01) and stage I (P=0.02) were associated with locoregional recurrence. The rate of metastasis was increased for advanced FIGO stages (P

Vaginal melanomas are rare genital malignancies occurring mainly in the 6th and 7th decades of life. In general, they have a worse prognosis than cutaneous melanomas. In the past, various treatment modalities have been recommended including radical pelvic surgery. However, the prognosis is poor in spite of such radical approaches. More recently, more conservative treatment in the form of wide local excision combined with adjuvant chemotherapy, high-dose radiotherapy, and immunotherapy seem to have promising results. We describe a patient with vaginal malignant melanoma treated with conservative local excision as well as adjuvant radiotherapy, chemotherapy, and interferon.

We conducted a retrospective review of the medical records of 18 patients diagnosed at the University of Colorado with perineal melanoma. Clinical characteristics including Clark's level, recurrence, and survival were studied. Ten patients (55.6%) had vulvar melanoma, 2 patients (11.1%) had vaginal disease, and the remaining 6 patients (33.3%) had primary rectal melanoma. All patients were treated surgically at the time of diagnosis. At a median follow-up of 32.7 months, 15 patients had evidence of recurrence. Nine of these patients are dead and six are alive with disease. The average time to recurrence was 14 months and the most common site was the regional lymph nodes in 10 of the 14 patients (71.4%). This study confirms the poor prognosis in perineal melanoma and the only effective treatment to date is early diagnosis and complete resection. © 1993 Wiley-Liss, Inc.

Background. Malignant melanomas of the vulva and vagina are rare tumors located in areas of the body not exposed to ultraviolet radiation. Investigations comprising large consecutive population-based series of patients with these diseases have not been published previously, to the knowledge of the authors. Methods. Trends in incidence, age distribution, and prognosis were investigated among 219 consecutive cases of malignant melanoma of the vulva and 26 cases in the vagina, reported to the Swedish National Cancer Registry and representing virtually all primary tumors of that kind in Sweden during a 25-year period, 1960–1984. Results. On average, 75% of the patients with vulvar melanoma and 73% with vaginal melanoma were older than 60 years of age. The mean age increased slightly but not significantly during the period. The age-standardized incidence of vulvar melanoma decreased from 0.27 to 0.14 per 100,000 Swedish women, or by 3% per year. The observed 5-year survival rate of patients with vulvar melanoma was 35%, and the relative survival rate was 47%. The observed and relative survival rates at 10 years were 23% and 44%, respectively. Observed and relative survival rates among patients with vaginal melanoma after 5 years were 13% and 18%, respectively. Conclusions. Accordingly, there was a decreasing incidence of vulvar and vaginal melanoma over the observed 25 years. This is in contrast to the trends in incidence for cutaneous melanomas in Sweden, which, during the same time period, increased almost 6% per year.

To describe the clinical and pathologic features of vaginal melanoma and to determine predictors of outcome in patients with this disease.Thirty-seven women with clinical and radiographic stage I vaginal melanoma treated at one institution between 1980 and 2009 were included in this retrospective study. Treatment modalities were assigned to one of three categories: pelvic exenteration, wide excision, and nonsurgical (primary radiation therapy, chemotherapy, or both). Overall survival and progression-free survival were calculated from the date of the surgical diagnosis.The median age was 60.6 years. Eighty-four percent of patients were white. Vaginal bleeding was the most common presenting symptom. Lesions were located in the distal third of the vagina in the majority (65%) of patients. Initial management included a wide local or radical excision (76% of patients); pelvic exenteration (14%); and radiotherapy, chemotherapy, or radiotherapy and chemotherapy (10%). At a median follow-up of 17.4 months, 33 women experienced disease recurrence. Recurrence was local only in seven patients (22%), distant only in 20 (63%), and both in five (15%). The most common sites of distant recurrence were lungs and liver. Median progression-free survival was 11.4 months, and median overall survival was 19 months. The 5-year progression-free and overall survival rates were 9.5% and 20.0%, respectively. Patients treated surgically had significantly longer survival than those treated nonsurgically (P=.01). Radiotherapy after wide excision reduced local recurrence risk and increased survival from 16.1 months to 29.4 months, although the increase was not significant (P=.46).Malignant vaginal melanoma, even when localized at presentation, has a very poor prognosis. Patients treated surgically have longer survival than those treated nonsurgically. Radiotherapy after wide excision reduces local but not distant recurrences.

Little is known on the difference in the incidence of vulvar and vaginal melanomas in various racial/ethnic groups. Population-based incidence of these melanomas in Asian and Hispanic individuals is almost unknown. Using 1992-2005 data provided by the National Cancer Institute's Surveillance, Epidemiology, and End Results Program, we calculated age-adjusted incidence rates of vulvar and vaginal melanomas in various racial/ethnic groups. From 1992 to 2005, there were 324 vulvar melanomas and 125 vaginal melanomas diagnosed in this group. The annual age-adjusted incidence rates (per million female population) of vulvar and vaginal melanomas in the different racial/ethnic groups was 0.87 (Blacks), 0.75 (American-Indian), 1.03 (Asians and Pacific Islanders), 1.22 (Hispanics), and 1.90 (non-Hispanic Whites). The overall white/black incidence ratio in vulvar and vaginal melanomas was 3.14 : 1 and 1.02 : 1, respectively; which is much less than that of cutaneous melanoma (13 : 1-17 : 1) and uveal melanoma (18 : 1) and is similar to that of conjunctival melanoma (2.6 : 1) and other mucosal melanomas (2.1 : 1-2.3 : 1). The low racial difference in vulvar and vaginal melanomas (as well as conjunctival and other mucosal melanomas) may be determined by their microenvironment factors (all originate from mucosa or semi-mucosa tissues). The incidence of vulvar and vaginal melanomas has does not increased in recent decades or toward the south (more sun exposure), indicating that ultraviolet radiation is not a causative factor in these melanomas. The slight decrease of incidence of vulvar melanoma in dark pigmented individuals may be related to the biochemical protective effects of melanin (as an antioxidant) rather than their photo-screen effects.

Primary malignant melanoma of the vagina is extremely rare, accounting for 0.3-0.8% of all malignant melanomas. True amelanotic vaginal melanoma showing no melanin on histological examination is exceedingly rare, accounting for only 2% of all vaginal melanomas.We describe a 31-year-old female patient who presented with locally advanced amelanotic melanoma of the vagina, with no evidence of metastatic spread on the computerized tomography (CT) scan, but who was subsequently diagnosed as suffering from metastatic disease by positron emission tomography (PET)-CT performed a few weeks following posterior pelvic exenteration.Specific immunohistochemical staining with melanoma markers should be performed to confirm or exclude a diagnosis of amelanotic melanoma in all patients presenting with a vaginal mass composed of undifferentiated epithelioid malignant cells. Fluorodeoxyglucose (FDG)-PET-CT should be performed as part of the preoperative evaluation, to identify the presence or absence of metastatic disease in all patients with vaginal melanoma.

We retrospectively analyzed clinicopathological findings in 10 cases of primary malignant melanoma of the vagina. The main presenting symptoms were vaginal bleeding, vaginal discharge, and feeling of a mass. The tumors were predominantly located in the lowest one-third and in the anterolateral aspect of the vagina. Patients underwent various surgical procedures, radiation therapy, and chemotherapeutic modalities. The mean survival time and the recurrence time from the time of diagnosis were 15 and 8 months, respectively. The tumors were examined for histological characteristics of cell type, presence of melanin pigment, depth of invasion, vascular invasion, intraepithelial spread, junctional activity, and mitotic count. Of all these histological variables, the mean survival time had a significant correlation to mitotic count (P less than 0.04). We concluded that patients with lower mitotic counts (less than 6 per 10 HPF) had better survival (21 months) compared to patients with mitotic counts greater than 6 per 10 HPF who had a mean survival of only 7 months.

Primary vaginal malignant melanoma is a very rare tumor with less than 300 cases reported to date. We describe a case of primary vaginal melanoma and review the literature. A 60 years postmenopausal female patient presented with painless mass coming out of the vagina with occasional bleeding for last 2-3 weeks. On vaginal examination there was a firm polypoidal growth of size 7 cm attached to the right lateral wall of vagina and coming out of the introitus. Histopathology of the mass showed features of malignant melanoma. Wide local excision was done and adjuvant therapy was given. However patient came back after three months with widespread metastasis and expired 6 months after the initial diagnosis. Vaginal melanoma is a very aggressive tumor and the overall prognosis is very poor despite the treatment modality.

Sentinel node (SN) biopsy is widely applied for treatment planning of cutaneous melanoma. However, using this strategy in female lower genital tract tumors has not yet been established. We report two cases, one each of vulvar and vaginal melanoma who underwent SN biopsy and review the available literature. Our experience and available limited evidence suggests that this low morbidity technique can be used for obtaining prognostic information and hence treatment planning for this disease. However, a false negative rate perhaps in the order of 15% suggests that careful consideration is necessary before using sentinel lymph node biopsy in the management of vulvar and vaginal melanoma.
