Background. Mullerian adenosarcoma with sarcomatous overgrowth (MASO) is a very rare variant of uterine sarcomas first described by Clement et al. as early as 1974. The presence of heterologous sarcomatous components is associated with aggressive biological behavior.Case Presentation. This is a case report of a 62-year female (P2 + 0) presenting with postmenopausal vaginal bleeding. Her preoperative USG revealed subserosal fibroid with adherent omentum. She underwent abdominal hysterectomy with bilateral oophorectomy. Histopathological diagnosis of resected specimen was Mullerian adenosarcoma with sarcomatous overgrowth and presence of heterologous elements involving body of the uterus. The whole thickness of the myometrium was involved along with the presence of serosal nodules and omental deposits of sarcomatous component.Conclusion. MA is considered as a low-grade malignant tumor, but MASO is a high-grade tumor frequently associated with invasion and metastasis with poor treatment outcome. Because of its rarity, correct identification of these tumors and distinction from other uterine sarcomas are a challenging job and hence its morphological features merits attention.

Mullerian adenosarcoma is an uncommon, but not rare, mixed tumor containing a neoplastic but benign or mildly atypical epithelial element and a sarcomatous, usually low-grade, stromal component. The most common site is the uterine corpus but adenosarcoma also occurs in the cervix and ovary and more rarely in the vagina, fallopian tube, arising from peritoneal surfaces, or outside the female genital tract, for example in the intestine. Most uterine cases have a polypoid gross appearance, sometimes resulting in the formation of multiple polyps. Characteristic histologic features include a low power "phyllodes-like" architecture with leaf-like projections lined by a variety of benign Mullerian type epithelia, sometimes with squamous metaplasia. Intraglandular stromal protrusions are a characteristic feature. The stroma may be uniformly cellular but there is typically increased cellularity around the epithelial elements, resulting in the formation of a cambium layer. Using the World Health Organization definition, stromal mitotic activity of 2 or more per 10 high-power fields is required for a diagnosis of adenosarcoma but in practice the diagnosis is made with stromal mitotic activity less than this if the characteristic architecture and cambium layer is present. The stromal component is usually morphologically "low-grade" and of endometrial stromal or fibroblastic type (hormone receptor and CD10 positive). Sometimes it is high grade, resembling undifferentiated sarcoma. Additional features sometimes present include heterologous stromal elements or sex cord-like differentiation. Uterine adenosarcomas are, in general, low-grade neoplasms capable of local recurrence after polypectomy or hysterectomy and much less commonly distant metastasis. The 2 most important adverse prognostic factors, which sometimes coexist, are deep myometrial invasion and sarcomatous overgrowth; the latter is usually associated with morphologically "high-grade" stromal elements with loss of expression of hormone receptors and CD10. Adenosarcoma may be confused with a variety of lesions and one of the main differential diagnoses is adenofibroma in which the stromal component is, by definition, morphologically benign. However, occasional adenofibromas recur or even metastasize. As such, it has been suggested that all adenofibromas should be classified as adenosarcomas, albeit with low-malignant potential. Ovarian adenosarcomas are much more likely to exhibit malignant behavior than their uterine counterparts, probably due to the lack of an anatomic barrier to peritoneal dissemination.

Background Mullerian adenosarcoma is a rare mixed epithelial–mesenchymal tumor. An extragenital site of origin and sarcomatous overgrowth are associated with aggressive clinical behavior. Case We present a rare case of extragenital adenosarcoma with sarcomatous overgrowth and coexistent endometriosis. She was treated with initial cytoreductive surgery and chemotherapy. She underwent a second surgery for management of a high-grade bowel obstruction, due to pathologically confirmed recurrent intraperitoneal adenosarcoma. A complete clinical response was achieved with liposomal doxorubicin, and the patient remains disease-free eighteen months after completion of chemotherapy. Conclusion Liposomal doxorubicin appears to be an active agent for the treatment of adenosarcoma with sarcomatous overgrowth. In addition, we conclude from our review of all reported cases of extragenital adenosarcoma that concurrent endometriosis may represent a favorable prognostic factor.

A case of müllerian adenosarcoma arising in ovarian endometriosis is reported in which the whole of the mesenchymal component exhibited striking deciduoid morphology, a phenomenon that has not been previously described. The patient was not taking hormonal preparations. We discuss the differential diagnosis and the possible pathogenesis of the deciduoid stromal alteration.

Mullerian adenosarcoma (MS) is a rare neoplasm of uterine cervix composed of benign epithelial and malignant stromal components. An aggressive variant of adenosarcoma, mullerian adenosarcoma with sarcomatous overgrowth (MASO) is extremely rare. The difference between MS and MASO is the pure high grade sarcoma features in MASO. In this report we present a MASO case, derived from uterine cervix of a 60 year-old-female patient presenting as a cervical polypoid mass, to our knowledge the second case of the English literature. In spite of sarcomatous overgrowth, high mitotic activity and huge tumor size of 12,5 cms, it displayed no myometrial invasion, vascular invasion and heterologous elements. The patient has been clinically free of disease for 14 months of follow up after total abdominal hysterectomy and bilateralsalpingo-oopherectomy. The difficulties in diagnosis and treatment of this entity will be evaluated in this report.

Müllerian adenosarcoma is a distinctive type of mixed Müllerian tumor of the female genital tract. To our knowledge, no cytogenetic data have been documented on Müllerian adenosarcoma in the literature so far. We report here the chromosomal findings of a Müllerian adenosarcoma in a 15-year-old female. Cytogenetic and molecular cytogenetic analysis revealed a complex karyotype involving chromosomes 2, 8, 10, 13, 19, and 21. These numerical and structural abnormalities may be of etiologic significance. This report may highlight the potential value of molecular cytogenetic analysis in differential diagnosis of Müllerian tumors. More cases are warranted to further genetically characterize this type of neoplasm.

We report four cases of mixed mullerian tumors of the endometrium arising in postmenopausal women taking tamoxifen for breast carcinoma. Various histopathologic features were encountered: one mullerian adenosarcoma and three malignant mixed mullerian tumors so called carcinosarcomas (in one case the sarcomatous component was homologous composed of tissues normally found in the uterus, while the others were heterologous because they were containing some elements normally not found in the uterus). Concern has been raised about prolonged tamoxifen treatment and subsequent occurrence of endometrial adenocarcinoma. Then, attention has been drawn through high-risk histologic subtypes including poorly differentiated patterns, uterine sarcomas and such mixed mullerian tumors. There is no consensus regarding internal surveillance of women receiving tamoxifen. The usefulness of pelvic sonography has not been demonstrated.

Müllerian adenosarkom daha çok postmenapozal dönemdeki kadınları etkileyen nadir bir tümördür. Patolojik olarak düşük gradeli endometrial stromal sarkom ve çoğunlukla benign, ama bazen de atipik glandüler epitelden oluşur. Hastalar çoğunlukla karın ağrısı, huzursuzluk ve uterin kanama şikayetiyle başvururlar. Bu yazıda abse formasyonuyla komplike olan ve postoperatif dönemde sepsis gelişen bir Müllerian adenosarkom olgusunu sunmayı amaçladık. Müllerian adenosarkomlar rölatif olarak iyi prognoza sahip nadir görülen tümörler olmakla birlikte klinik tablo nekroza sekonder gelişen enfeksiyon, abse gelişimi ve postoperatif sepsisle komplike olabilmektedir

Background. Mullerianadenosarcoma is a rare pelvic malignancy that most commonly arises from the endometrium. These tumors are relatively insensitive to chemotherapy and radiation and are primarily treated by surgical resection. We report a case of mullerian adenosarcoma arising outside of the uterus from a background of endometriosis treated with a combination of surgical resection and medroxyprogesterone acetate. Case. A 43-year-old woman with a history of endometriosis was diagnosed with advanced extrauterine mullerian adenosarcoma. After suboptimal tumor dubulking surgery she was treated with medroxyprogesterone acetate. Ten months postoperatively she remains without evidence of disease. Conclusion. Medroxyprogesterone acetate may be a useful drug in the treatment of advanced mullerian adenosarcoma.

We report a primary peritoneal mullerian adenosarcoma with sarcomatous overgrowth associated with endometriosis in a 50-year-old female. The tumor formed multiple peritoneal masses occupying the pelvis and subdiaphragmatic space. Histologically, the tumor was composed of benign-appearing mullerian glands surrounded by a sarcomatous stroma. In addition, one perisplenic mass was largely devoid of the epithelial component and was of higher grade than the remaining lesions. Multiple foci of endometriosis were associated with the pelvic masses. To our knowledge, primary peritoneal mullerian adenosarcoma with sarcomatous overgrowth associated with endometriosis has not been previously reported.

Uterine adenosarcoma has poor prognosis and management of this disease is controversial. We describe a case of sarcomatosis secondary to recurrent uterine adenosarcoma who underwent cytoreductive surgery (CS) and hyperthermic intraoperative peritoneal chemotherapy (HIPEC). A 52 year-old female presented with perimenopausal menometrorrhagia. She underwent laparoscopic hysterectomy and bilateral salpingo-oopherectomy with pathology showing uterine adenosarcoma. She developed a pelvic recurrence 2 years later. A pelvic exenteration was then performed and within 8 months, she recurred. CS/HIPEC with Cisplatin was performed. Six weeks post-operatively, the patient was found to have recurrence again. This case describes the use of CS/HIPEC as a treatment modality for uterine adenosarcoma with sarcomatosis. Despite CS and HIPEC, the patient developed an aggressive recurrence within six weeks of her surgery date. We recommend a multidisciplinary approach to this disease with the recognition that CS/HIPEC may offer little benefit as a salvage therapy based on this case.

Mullerian adenosarcomas of the female genital tract are rare malignancies, originally described in the uterus, the most common site of origin, but they may also arise in extrauterine locations. Uterine adenosarcomas make up 5% of uterine sarcomas and tend to occur in postmenopausal women. They are usually low-grade tumors and are characterized by a benign epithelial component with a malignant mesenchymal component, which is typically a low-grade endometrial stromal sarcoma but can also be a high-grade sarcoma. Tumors that exhibit a high-grade sarcomatous overgrowth have a worse outcome. Adenosarcomas have been described as being midway along the spectrum between benign adenofibromas and carcinosarcomas. They generally have a good prognosis with the exception of deeply invasive tumors or those with high-grade sarcomatous overgrowth. Extrauterine adenosarcomas also have a higher risk for recurrence. In view of their rarity, there have not been any clinical trials in mullerian adenosarcomas and relatively little research. This article reviews the current knowledge and provides recommendation for the management of mullerian adenosarcomas.

Objective: To review the literature on tamoxifen side effects on the female genital tract and psychosexual function in premenopausal and postmenopausal women. Data Sources: We used the English-language literature in MEDLINE and reference lists from selected articles. Search terms included: "tamoxifen and estrogen receptor," "transcription activation," "premenopause," "postmenopause," "vaginal epithelium," "uterus," "endometrial hyperplasia," "polyps," "endometrial cancer," "sonography," "sonohysterography," "hysteroscopy," "myometrium," "myoma," "sarcoma," "endometriosis," "ovarian cysts," "hot flushes," "concentration problems," "sleep disturbance," "vaginal dryness," "sexual function," "libido," "dyspareunia," and "quality of life." No study-type restrictions were imposed. Methods of Study Selection: With respect to clinical studies we included case cohort studies, observational studies; if no trials were available on a subject, case reports published in peer-reviewed journals were selected. For the discussion on endometrial surveillance of tamoxifen users, letters and editorials published in peer-reviewed journals also were used. Subjects of interest were mechanism of action of tamoxifen, tamoxifen and the vaginal epithelium, endometrium, mesenchymal tumors of the uterus, ovaries, sexual function, and vasomotor instability. Tabulation, Integration, and Results: Eligible studies were analyzed to determine their usefulness in this review. Data from trials that evaluated tamoxifen side effects on specific genital tissues were combined, with special interest in differentiation of side effects in premenopausal and postmenopausal women. Weighted estimates of severity and extent of side effects were usually not possible because of lack of randomized trials. Only the risk of endometrial cancer in relation to tamoxifen treatment could be estimated. Conclusion: The gynecologic side effects of tamoxifen are diverse and reflect the complexity of its mechanism of action, with agonistic and antagonistic effects on various tissues, depending on the ambient estradiol concentration and hence menopausal status of the patient. The most frequently reported side effect was hot flushes, and the most worrisome gynecologic side effect was a two- to three-fold increased risk of endometrial cancer in postmenopausal women. Despite its side effects, the benefits of tamoxifen in controlling breast cancer or prevention of its relapse are still without debate.

Müllerian adenosarcoma is a rare biphasic tumor in young women. These tumors can recur even after complete resection. We present a patient treated with oral progesterone after hysterectomy with ovary conservation. A 35-year-old woman had a diagnosis of adenosarcoma on hysteroscopic resection, which was estrogen and progesterone receptor positive. She underwent total hysterectomy with ovary conservation and has received oral medroxyprogesterone acetate treatment. At 15 months after surgery, there has been no disease recurrence. Oral medroxyprogesterone acetate therapy can be used effectively in young women with müllerian adenosarcoma whose ovaries are preserved.

A case of extrauterine Müllerian adenosarcoma of the peritoneum in a 20-year-old woman is reported. The tumor was widely based on the abdominopelvic wall and there were no unusual features in the genital organs. The cut surface of the tumor showed a marked gelatinous appearance. The tumor was composed of an admixture of benign Müllerian-type epithelium and sarcomatous stroma. The predominant element of the sarcomatous area was rhabdomyosarcoma, which showed a close resemblance to well-differentiated embryonal rhabdomyosarcoma. In another sarcomatous area, fibroblastic cells without myoblastic properties diffusely proliferated in a marked myxoid background with some collagen bundles. Both the mitotic count and Ki-67 proliferative index of these cells were lower than those of rhabdomyoblastic cells. On follow up, the patient was disease free for 1 year postoperatively, without any subsequent treatment. The present case indicates that extrauterine adenosarcoma can also show histological heterogeneity as do uterine adenosarcomas. The remarkable myxoid change of this tumor seemed to be more largely due to a fibromyxoid element than a rhabdomyosarcomatous element, and the coexistence of the former may be related to the less aggressive behavior of this tumor.

Müllerian adenosarcoma with sarcomatous overgrowth presented by a 52-year-old female patient after adjuvant tamoxifen treatment for breast carcinoma is described. The diagnosis was made on histological basis after curettage and complementary total hysterectomy with bilateral salpingo-oophorectomy. The immunohistochemical study showed high expression of estrogen receptors in the epithelial component of the lesion and irregularly positive findings in the stroma. The proliferative activity evaluated by Ki-67 immunoexpression was higher in the stroma than the epithelium. Some of the stromal cells showed rhabdomyoblastic differentiation. The association of tamoxifen use and development of mesenchymal neoplasms is discussed. É descrito o caso de uma paciente do sexo feminino, 52 anos, com adenossarcoma Mülleriano com componente sarcomatoso predominante, que se apresentou após tratamento adjuvante com tamoxifeno para câncer de mama. O diagnóstico foi feito em bases histológicas após curetagem uterina e histerectomia total complementar com anexectomia bilateral. O estudo imuno-histoquímico mostrou alta expressão de receptores de estrogênio no componente epitelial da lesão e positividade irregular no estroma. A atividade proliferativa avaliada através da imunoexpressão do Ki-67 foi maior no estroma do que no epitélio. Algumas células estromais mostraram diferenciação rabdomioblástica. A associação entre uso de tamoxifeno e desenvolvimento de neoplasias mesenquimais é discutida.

Müllerian adenosarcoma is a rare neoplasm that can arise in both uterine and extrauterine locations. This report describes the ultrasound and magnetic resonance imaging findings of one case of ovarian adenosarcoma and reviews the literature as to the previously described imaging findings. Adenosarcoma should be considered in patients with a predominantly solid pelvic mass on imaging, particularly in those with a history of endometriosis or findings compatible with endometriosis on ultrasound or magnetic resonance imaging. A very low resistive index on ultrasound may also be suggestive of this diagnosis.

A 71-year-old patient developed an uterine adenosarcoma two months after two years of tamoxifen adjuvant treatment for early breast cancer. After curettage for postmenopausal bleeding, the patient underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy and pelvic lymphadenectomy. Histologic examination revealed an adenosarcoma of the uterus without myometrial invasion or lymphatic spread. After four years of follow-up, there was no evidence of recurrent disease. The possible association between tamoxifen treatment and uterine sarcoma is discussed.

Highlights • Two cases of large cervical mullerian adenosarcoma with sarcomatous overgrowth or heterologous elements and contrasting survival outcomes are reported. • When the diagnosis of mullerian adenosarcoma is uncertain or suspected, review of pathology by a national expert may be considered. • Rhabdomyoblastic differentiation of mullerian adenosarcoma may be a more aggressive histologic type.

Background: Extragenital Müllerian adenosarcomas are extremely rare tumours characterised by a stromal component of low-grade malignancy and by a benign glandular epithelial component. Case Report: A 26-year-old woman was admitted to our clinic because of lower abdominal distension and left lower quadrant pain. Clinical and radiological examinations suggested an ovarian malignancy. Laparotomy revealed a cystic mass in the pouch of Douglas, originating from the left sacrouterine ligament. A total excision of the tumour was performed and showed low-grade adenosarcoma without sarcomatous overgrowth. Follow-up at 24 months after the surgery showed no evidence of recurrence. Conclusion: Mullerian adenosarcoma located in the pouch of Douglas is rare. For treatment, success may be achieved with only excision of the tumour if there is no sarcomatous overgrowth or spread to adjacent tissues.

Background Endometrial stromal sarcoma (ESS) is a term used to define a rare neoplasm that accounts for approximately 0.2%-1% of all uterine malignancies; it is, however, implicated in an estimated 10%-15% of those malignancies with a mesenchymal component. Recent evidence suggests that while the preservation of the ovaries may be considered appropriate in premenopausal women, hysterectomy and bilateral salpingo-oophorectomy remains the recommended treatment in postmenopausal women. Currently, only a few case series reporting the treatment of ESS in young women with a desire to preserve fertility and thus subjected to a fertility-sparing surgery are available in the literature. Case presentation We report a peculiar case of early stage ESS treated by laparoscopic fertility-sparing surgery and a strict follow-up program (every 3 months) of imaging and clinical evaluation. The patient remained disease free 1 year after primary treatment. Three months after completing oncological follow-up, the patient conceived spontaneously and is, to date, pregnant at 11 weeks of gestation without evidence of recurrent disease or obstetric complications. Conclusion Based on our case report and in accordance with the data available, we suggest that in young patients affected by early stage ESS who wish to preserve reproductive function, fertility-sparing surgery could represent a valid option, though strict oncological follow-up remains mandatory.

We present a case of a liver endometrioma in a postmenopausal woman. After failed management with leuprolide acetate, the mass was resected and contained focal areas of mullerian adenosarcoma. This is a rare case of mullerian adenosarcoma that appeared to arise within an endometrioma of the liver.

Uterine adenosarcoma is an extremely rare uterine malignancy, and the utility of chemotherapy in this disease is not well defined. This study assessed the safety and efficacy of trabectedin in patients with recurrent/metastatic uterine adenosarcoma with sarcomatous overgrowth. A retrospective search of a prospectively maintained database was performed to identify patients with adenosarcoma treated with trabectedin between 2010 and 2012, within a compassionate use trial. Three patients with recurrent/metastatic uterine adenosarcoma treated with trabectedin were identified. All three patients tolerated the drug well. Two patients obtained prolonged clinical benefit from treatment, one having received 17 cycles and another 11 cycles of therapy. Trabectedin is well tolerated and has clinical activity in recurrent/metastatic uterine adenosarcoma.

Müllerian adenosarcomas of the uterus usually present as pedunculated endometrial masses in postmenopausal women with vaginal bleeding. Extraendometrial variants (originating in the ovary, adnexa, or myometrium) are much less common, and they tend to present at a more advanced stage due to their location. The sarcomatous portion of müllerian adenosarcoma can vary from low grade to very high grade and the clinical behavior of the tumors can be indolent or aggressive. We present two cases, one of which originated in the adnexa and the other in an apparent focus of uterine adenomyosis. These cases illustrate the difficulty of correct diagnosis and treatment.

Mullerian adenosarcomas are rare tumours that may be found in any part of the female genital tract including cervix. They are more common in the reproductive age group and rare among blacks. When they present in the cervix they may be clinically misdiagnosed as an endocervical polyp and histologically as an adenofibroma. Clinical presentation is mostly as irregular vagina bleeding and as a mass in the vagina. Meticulous histopathological evaluation is crucial for its optimum management.

We report a case of uterine adenosarcoma demonstrated on magnetic resonance (MR) imaging. A 74-year-old woman with a large uterine mass underwent MR examination before total abdominal hysterectomy. Imaging revealed a markedly enlarged uterus with thin myometrium occupied by a large polypoid mass. The mass contained solid components with low intensity on T(1)-weighted images and high intensity on T(2)-weighted images compared to the myometrium and areas of small cysts.

Non-puerperal uterine inversion due to uterine sarcomas represents a very rare event with no reliable estimate of frequency in the literature. Clinically, the diagnosis of inversion may be difficult, as far as imaging procedures are concerned, although ultrasonography may prove to be useful. However, some characteristics such as the indentation of the fundic area and a depressed longitudinal groove extending from the uterus to the center of the inverted portion are difficult to recognize. Moreover, there is no specific computed tomography feature accurate enough to aid in the differential diagnosis. Here, we report a case of uterine inversion due to Mullerian uterine adenosarcoma whose preoperative workup and diagnosis took advantage of the application of magnetic resonance imaging.

A case of uterine Mullerian tumor in an adolescent is described. Surgical and clinical management is discussed, based on the experience gained by the analysis of cases described in the literature. A review of the different age groups, primary sites, surgical management and biological behavior of cases described in the literature is tabulated and analysed.

Introduction Uterine adenosarcoma is a rarely observed polypoid tumor with a mixed benign epithelial element and malignant stromal component. The treatment is total hysterectomy with bilateral salpingo-oophorectomy. It could be difficult to diagnose and associated to lymphovascular invasion. Case presentation A 45-year-old caucasian uniparous woman presented with uterine bleeding. She had several surgical procedures and pathology of removed recurrent polyps showed no malignancy. Finally, a total abdominal hysterectomy was performed because of atypical cells and suspected uterine adenosarcoma. The hysterectomy specimen confirmed the presence of uterine adenosarcoma associated with lymphatic and vascular tumor emboli. Surgery was completed with a second bilateral salpingo-oophorectomy and pelvic lymphadenectomy. Conclusion In our report, we present a case of uterine adenosarcoma which was diagnosed after multiple surgical procedures and associated to lymphovascular emboli known to have a significant impact on overall survival and distant metastasis-free survival.

Uterine adenosarcoma (AS) are rare tumors and have more favorable outcomes than the aggressive uterine carcinosarcomas. Uterine adenosarcoma with sarcomatous overgrowth (ASSO) is a variant form of AS and exhibits aggressive growth of tumor and the prognosis is relatively poor compared with typical AS. Usually patterns of metastasis have been known to behave like endometrial carcinoma and spread through the lymphatics. Brain metastasis from uterine AS is extremely rare. Herein, we report a case of successfully surgically removed solitary brain metastasis without any extracranial recurrence from uterine ASSO after 4 years of primary treatment.

Mullerian adenosarcoma with sarcomatous overgrowth (MASO) is a rare variant of uterine sarcomas, associated with postoperative recurrence, metastases and a fatal outcome. The mean age at diagnosis is 54.5 years. A 37-year-old nullipara presented with irregular vaginal bleeding, a normal pelvic examination, and an initially negative ultrasound. Repeat ultrasound one month later revealed an 11-cm heterogeneous pelvic mass. She underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Pathology confirmed uterine MASO. Computed tomography 2 weeks postoperatively showed a huge mass compatible with recurrence. Patient died 2 weeks later. MASO is rarely diagnosed in women in their 4th decade. This case stresses that these aggressive tumors should be considered in the differential of patients with vaginal bleeding and pelvic masses irrespective of their age.

Fertility-sparing and minimally invasive surgeries are advancing everyday in gynecologic oncology. However, data on conservation of ovaries in uterine mullerian adenosarcoma are limited due to its very rare incidence in reproductive-aged females. Conservation of both ovaries along with adjuvant chemotherapy was performed in a 14-year-old girl with uterine adenosarcoma. After 30 months, she had no evidence of disease. Therefore, surgical conservation of ovaries might be a solution for fertility sparing in uterine mullerian adenosarcoma. (c) 2007 AAGL. All rights reserved.

Background Mullerian adenosarcoma of the uterine cervix is a rare tumor seen in young women of reproductive age group. It presents as cervical polyps and is a low-grade malignancy with a tendency for local recurrence. Diagnosis can be difficult since it can easily be mistaken for benign polyps, both clinically and pathologically. Case We present three cases of adenosarcoma of the cervix presenting as cervical polyps and review the clinical and pathological features of these tumors. Conclusion Adenosarcoma of the cervix should be ruled out especially in women presenting with recurrent cervical polyps. A careful histological examination is mandatory, important prognostic factors being myometrial invasion and sarcomatous overgrowth. Distant metastasis is very rare and therapy can be tailored to suit patient's needs but long term follow-up is essential.

Adenosarcoma is a rare uterine biphasic tumor composed of benign epithelial elements and a sarcomatous stroma. Although it is well described histologically, its cytological features are rarely mentioned in the literature. We describe a case of uterine adenosarcoma that was first detected by Papanicolau (Pap) smear. Numerous crowded clusters of spindle cells were present within a bloody background, as well as a few smaller, dyscohesive groups with cells showing high N:C ratio and oval to round nuclei with coarse chromatin and small nucleoli. A few nuclear grooves were identified. Adenosarcomas are rare lesions but should be considered in the differential diagnosis when spindled cells are noted in a pap smear. Diagn.

Paciente de 27 años, nuligesta, consultó por sangrado genital irregular de aproximadamente 4 meses de evolución. El examen ginecológico reveló una masa blanda que salió a través del orificio cervical externo. En la ecografía pélvica se evidenció útero aumentado de tamaño, con cavidad uterina ocupada por masas amorfas con pequeñas áreas anecoicas-ecolúcidas en su interior. El informe de anatomía patológica indicó tumor mülleriano mixto, polipoide, benigno tipo adenofibroma de origen endometrial. A los 3 meses, la paciente presentó reaparición de la sintomatología por lo cual se decide prepararla para realizarle histerectomía. Durante este período ingresa con diagnóstico de abdomen agudo quirúrgico, obstrucción intestinal y deshidratación moderada, realizándose histerectomía total ampliada y ooforosalpingectomía bilateral más omentectomía. El informe de anatomía patológica reportó adenosarcoma mülleriano de origen endometrial. A 27 years-old patient consulted for irregular genital bleeding of approximately four months of evolution. Gynecologic exam revealed a soft mass that exit trough external cervical os. Pelvic ultrasonography showed a large size uterus, with an uterine cavity occupied by amorphous mass with little anechoic - echo lucid areas inside. Pathology report indicated a mixed polyploid, adenofibroma type, benign müllerian neoplasia of endometrial origin. At seven months, patient presented reappearance of symptoms, deciding to prepare for a hysterectomy. During this period, patient is admitted with diagnosis of surgical acute abdomen, intestinal obstruction and moderate dehydrated, performing hysterectomy and bilateral oophorosalpingectomy plus omentectomy. Pathology reported müllerian adenosarcoma of endometrial origin.
