The Pap smear has been in use for more than half a century as the primary screening test for preinvasive and invasive lesions of the uterine cervix. Although not the primary use and an imperfect test, it can be extremely useful in the diagnosis of some microorganisms. This review focuses on the use of the Pap smear in the diagnosis of several microorganisms including Actinomyces, Chlamydia trachomatis, Candida, Trichomonas vaginalis, Leptothrix vaginalis, Herpes Simplex Virus, the causative agents of bacterial vaginosis, and other rarer organisms. The accuracy of diagnosis using the smear varies among the different organisms in question. [ABSTRACT FROM AUTHOR]

Objective: Epidural steroid injections (ESIs) are widely used in clinical practice for the treatment of low back radicular pain. Anecdotally it has been conveyed that the reproduction of a patient's usual pain during ESI was of prognostic value as to which patients would show favorable results from the procedure, however, there is no data available to support this supposition. Design: Retrospective. Setting: Outpatient Spine and Sports Medicine Clinic. Patients: Patients with lumbosacral radicular pain treated with fluoroscopically guided contrast enhanced lumbosacral transforaminal ESI. Outcome Measures: 11-point pain intensity numeric rating scale (PI-NRS). Results: Overall the procedure provided statistically significant pain relief in both groups A (typical radicular pain reproduced) and B (typical radicular pain not reproduced) immediately and significant pain reduction was maintained until the time of the follow-up No reduction in pain was seen in group A vs. B, although in group B there was a strong trend toward having higher pain scores at all times. Conclusion: The reproduction of a patient's typical radicular pain during a fluoroscopically guided contrast enhanced lumbosacral transforaminal ESI does not predict a significant decrease in pain scores immediately after the procedure or at follow up.

The 2001 Bethesda System for Reporting Cervical Cytology recommends reporting benign exfoliated endometrial cells in women age 40 and older, and a review of the literature supports this recommendation. Stromal cells and histiocytes do not need to be reported. The effect of hormonal therapy on endometrial shedding is reviewed. Clinical information should be provided to the laboratory so that appropriate educational notes can be appended to the cytology report. Benign endometrial cells in premenopausal women in the first half of the cycle are not associated with significant pathology and such women do not need additional evaluation. Significant pathology is also unlikely in the second half of the cycle and evaluation may not be required unless clinically indicated. Initial evaluation of other women with benign endometrial cells may include either endometrial sampling or transvaginal ultrasound. Atypical endometrial cells are associated with a higher rate of significant pathology and should lead to additional evaluation. Additional prospective studies on the management of patients with endometrial cells on Pap tests are needed. [ABSTRACT FROM AUTHOR]

OBJECTIVE.: Recently, an immunohistochemical test for her-2-neu has been approved by the Food and Drug Administration for evaluation of breast cancer patients who might benefit from treatment with Herceptin (HercepTest). This study was undertaken to evaluate the immunohistochemical staining patterns in cervical cancer and correlate with clinical parameters. MATERIALS AND METHODS.: A total of 24 cases of invasive squamous cell carcinoma of the cervix were evaluated. Cases were stained using the HercepTest kit according to protocol. Results were graded from 0 to 3+, using the standards set for breast lesions. RESULTS.: A total of 17 cases (70.8%) were negative, 3 cases (12.5%) showed 1+ staining, and 4 cases (16.7%) showed 2+ staining. No cases showed 3+ staining. Higher her-2 staining grade correlated strongly with vaginal margin status. A weak positive correlation was seen between her-2 staining and tumor stage. There was no correlation with tumor grade or histological lymph node status. CONCLUSIONS.: A subset of invasive squamous cell carcinomas of the cervix overexpress her-2 protein. Further studies are needed to correlate with clinical outcome and determine if overexpression of her-2 protein is a marker of cervical carcinoma aggressiveness. [ABSTRACT FROM AUTHOR]

Objective: Bacterial vaginosis (BV) is associated with significant morbidity. Bacterial vaginosis is due to an overgrowth of anaerobic organisms in the vagina. It has been postulated that the presence of Trichomonas creates an anaerobic environment that favors BV. Thus, BV should be more frequent in the presence of Trichomonas if Trichomonas is creating a favorable anaerobic environment.Materials and Methods: A retrospective review of Pap test reports was performed for a diagnosis of coccobacilli consistent with shift in vaginal flora, that is, the presence of clue cells. Cases were Pap smears with Trichomonas identified. Controls were cases without Trichomonas. Results were analyzed using Fisher exact test.Results: Four hundred cases were reviewed; 200 with and 200 without Trichomonas. The incidence of BV was significantly higher in the Trichomonas group (46.5%) than in group without Trichomonas (24.5%) (p < .0001.).Conclusion: The presence of Trichomonas on a Pap smear is associated with an increased incidence of BV. The report of Trichomonas on a Pap smear should prompt clinical consideration that BV may be present. [ABSTRACT FROM AUTHOR]

Sebaceous hyperplasia is a cutaneous lesion consisting of soft, yellow, papular lesions usually occurring on the face in elderly patients. The occurrence of the lesion on the vulva is exceptionally rare. We were able to identify only three cases reported in the literature. We report a case of sebaceous hyperplasia of the vulva with an unusual presentation. [ABSTRACT FROM AUTHOR]

Adenomyoma of the cervix is a rare benign neoplasm, one of a group of benign endocervical lesions that may histologically be confused with an aggressive cervical carcinoma, adenoma malignum. We recently encountered a case that distorted the cervix and pushed it under the pubic symphysis. We present this case, review the literature of this rare lesion, and discuss the differential diagnosis of this group of endocervical lesions. [ABSTRACT FROM AUTHOR]

Lymphoepithelioma is well known in the nasopharyngeal region. Although this neoplasm is well described in a variety of extranasal sites, where it is termed lymphoepithelioma-like carcinoma, this is only the second report of this neoplasm originating in the vulva reported in the literature. These lesions are reported to be less aggressive in extranasal sites. A 40-year-old woman presented with a lymphoepithelioma-like carcinoma of the vulva, diagnosed by excisional biopsy, which had been present for 1 month. The lesion persisted with ipsilateral lymph node involvement 4 months after initial resection, when the patient returned for definitive surgery. Lymphoepithelioma-like carcinoma can occur rarely in the vulva, and may behave aggressively. [ABSTRACT FROM AUTHOR]

Introduction: Cervical cytology remains a critical screening tool for cervical cancer. While various factors can influence cytology quality, the effect of lubricant type used during specimen collection has been previously studied with inconclusive results. This study aimed to evaluate the impact of surgical lubricant on cervical cytology results and elucidate risk factors associated with unsatisfactory results. We hypothesized that switching from a carbomer-containing lubricant to a noncarbomer, water-soluble lubricant would improve specimen adequacy in cervical cytology., Materials and Methods: A retrospective chart review was performed examining patient cytologic results from January to December 2017 at a single academic institution. After historical rates of unsatisfactory cytology were higher than acceptable standards, the practice changed lubricant formulation from a carbomer containing lubricant to a noncarbomer, water soluble lubricant. Demographic data and treatment characteristics were collected for eligible patients. Matched analysis was performed to examine factors associated with an unsatisfactory cytology result., Results: After the change in lubricant, there was a significant decline in the rates of unsatisfactory cytology from 9.6% to 5.7%, P = 0.01. This decline was also observed when patients were matched based on menopausal status, personal history of gynecologic malignancy, pregnancy status, and cytology specimen type (10.0% to 4.8%, P = 0.001)., Conclusions: Change in lubricant from a carbomer containing to noncarbomer, water soluble product was associated with a statistically significant decline in the rates of unsatisfactory cytology. Although prior data have had mixed results as to the etiology of unsatisfactory cytology, we feel that this directly contributed to the high rates observed at our institution., (Copyright © 2024 American Society of Cytopathology.

Uterine involution has 2 major components-(1) involution of vessels; and (2) involution of myometrium. Involution of vessels was addressed by Rutherford and Hertig in 1945; however, involution of myometrium has received little attention in the modern literature. We suggest that the pathophysiology of myometrial involution may lead to uterine atony and postpartum hemorrhage. The myometrium dramatically enlarges due to gestational hyperplasia and hypertrophy of myocytes, caused by hormonal influences of the fetal adrenal cortex and the placenta. After delivery, uterine weight drops rapidly, with physiologic involution of myometrium associated with massive destruction of myometrial tissue. The resulting histopathology, supported by scientific evidence, may be termed "postpartum metropathy," and may explain the delay of postpartum menstrual periods until the completion of involution. When uterine atony causes uncontrolled hemorrhage, postpartum hysterectomy examination may be the responsibility of the perinatal pathologist.Postpartum metropathy may be initiated when delivery of the baby terminates exposure to the hormonal influence of the fetal adrenal cortex, and may be accelerated when placental delivery terminates exposure to human chorionic gonadotrophin (HCG). This hypothesis may explain why a prolonged third stage of labor, and delays in management, are risk factors for severe hemorrhage due to uterine atony., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Pathologic examination of the placenta can provide insight into likely (and unlikely) causes of antepartum and intrapartum events, diagnoses with urgent clinical relevance, prognostic information for mother and infant, support for practice evaluation and improvement, and insight into advancing the sciences of obstetrics and neonatology. Although it is true that not all placentas require pathologic examination (although alternative opinions have been expressed), prioritization of placentas for pathologic examination should be based on vetted indications such as maternal comorbidities or pregnancy complications in which placental pathology is thought to be useful for maternal or infant care, understanding pathophysiology, or practice modifications. Herein we provide placental triage criteria for the obstetrical and neonatal provider based on publications and expert opinion of 16 placental pathologists and a pathologists' assistant, formulated using a modified Delphi approach. These criteria include indications in which placental pathology has clinical relevance, such as pregnancy loss, maternal infection, suspected abruption, fetal growth restriction, preterm birth, nonreassuring fetal heart testing requiring urgent delivery, preeclampsia with severe features, or neonates with early evidence of multiorgan system failure including neurologic compromise. We encourage a focused gross examination by the provider or an attendant at delivery for all placentas and provide guidance for this examination. We recommend that any placenta that is abnormal on gross examination undergo a complete pathology examination. In addition, we suggest practice criteria for placental pathology services, including a list of critical values to be used by the relevant provider. We hope that these sets of triage indications, criteria, and practice suggestions will facilitate appropriate submission of placentas for pathologic examination and improve its relevance to clinical care., (Copyright © 2022 The Author(s).

Objectives: Neoplasms arising from the vulva are uncommon and comprise various subtypes. Given the recent advancements in the molecular aspects of oncologic pathology and how they have impacted cancer treatment, an understanding of recent innovations in the molecular features of vulvar lesions is important., Materials and Methods: Systematic literature search was performed on PubMed, Google Scholar, and Scopus databases for molecular and genetic characteristics of vulvar neoplasms. Peer-reviewed literature published in English is included., Results: Squamous cell carcinoma (SCC) and its precursors are the predominant neoplasm at this site. Human papillomavirus (HPV) plays a crucial role in the pathogenesis of some of these lesions. Human papillomavirus-associated SCC follows the carcinogenic pathway driven by viral proteins E6 and E7 while HPV-independent SCC shows a high incidence of mutation of TP53 and CDKN2A genes. Mutations in the genes involving the PI3K-Akt pathway play an important role in the pathogenesis of both types of SCC. Among other vulvar malignancies, melanoma, and vulvar Paget disease (VPD) pose a significant clinical challenge and have unique molecular characteristics. Compared with dermal cutaneous melanoma, vulvar melanoma shows a higher rate of mutation of cKIT and NRAS genes and a lower rate of mutations in BRAF . Less than 20% of VPD shows amplification of ERBB2 and seldom shows mutation in genes involving the PI3K-Akt pathway., Conclusions: Several potentially targetable molecular pathways have emerged as they have been shown to be involved in the tumorigenesis of SCC, melanoma, and VPD., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2022, ASCCP.)

Carcinomas metastatic to the brain are common, however, metastatic disease to the hypothalamic- pituitary region is uncommon and account for less than 3.6% of all resected malignant pituitary tumors. Most metastatic disease in that region derives from a lung or breast primary, with both ductal and lobular carcinoma reported. We report what we believe is the first case of pleomorphic lobular carcinoma metastatic to the hypothalamus. This case is also reaffirms that late metastasis from breast cancer should be considered in the differential diagnosis. It is important for the clinician to consider the clinical history of breast cancer, even when remote, in the differential diagnosis.

Primary uterine angiosarcoma is an extremely rare neoplasm. Due to its rarity, knowledge regarding this malignancy is limited to a few scattered case reports. To better understand the prognostic factors and optimal management of these neoplasms, we have performed a systematic analysis of the disease. A systematic literature search of this entity yielded 25 reported cases of this entity. In addition, we searched the National Cancer Institute Surveillance, Epidemiology, and End Results database to find 4 additional cases and added a case diagnosed in our institution. We analyzed the patients' demographic characteristics and the different treatment protocols utilized to treat this malignancy. Patients were primarily treated by surgery with or without adjuvant chemotherapy and radiotherapy. Survival analysis was performed to examine the role of various factors in the outcome for the patients. There was no correlation with age of diagnosis, or treatment modality used, however, better outcomes were seen in patients presenting with smaller sized tumors. Our study is the first attempt to systematically study this rare malignancy in hopes of leading to a more standardized, evidence-based, and improved treatment protocol., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 by the International Society of Gynecological Pathologists.)

Background Idiopathic indentation of the cardiac ventricles in a fetus has not been previously reported. Reported cases of congenital ventricle indentation are either caused by pericardial abnormalities or myocardial defects. Case report : We describe an incidental finding of annular indentation of the lower part of both ventricles in a stillborn male. The fetus was well-developed and the cause of stillborn was pronounced cord entanglement twice around the neck. Conclusion: Circumferential indentation of ventricles is distinguished from constrictive pericarditis and other myocardial defects as histologically the three layers of endocardium, myocardium, and pericardium are intact.

Endometrial stromal sarcoma (ESS) is the second most common uterine mesenchymal neoplasm. ESS can arise from extrauterine locations without any uterine involvement and is called extrauterine ESS (EESS). The epidemiological features of EESS are not well-known. Moreover, the factors affecting its outcome have not been systemically studied. The treatment of EESS closely follows that of uterine ESS, comprised of different combinations of surgical management, hormone therapy, chemotherapy, and radiation therapy. However, the effectiveness of different treatment protocols for EESS has not been studied. Here, we have performed a systematic review of all reported cases of EESS in the English literature. We further performed a meta-analysis of the outcome data and investigated how the patients' age, tumor site, tumor size, and management affect the overall and progression-free survival of the patients. We found that tumor site and mode of treatment significantly affected the overall survival and progression-free survival of the patients. Tumor size significantly affected overall survival but not progression-free survival, while the age at diagnosis did not affect patient outcome. As far as we know, ours is the first systematic study of this rare malignancy with an emphasis on outcome analysis., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Chorangioma is the most common type of primary non-trophoblastic tumor of the placenta, usually identified incidentally on ultrasound or at delivery. Leiomyomas within the placenta have been described, though they are rare and usually of maternal origin. We present an unusual case of a placental tumor with combined histopathologic and immunohistochemical features of both chorangioma and leiomyoma. A 39-year-old woman was found to have an echogenic placental mass at 33 weeks of gestation on ultrasound, that was thought to be a chorangioma. They followed up weekly, and performed a cesarean section at 39 weeks, due to concern for intrauterine growth restriction. No fetal or maternal complications occurred. Grossly, a 9-cm, red-brown mass with a broad-based stalk was identified on the fetal surface of the placenta near the periphery. Microscopically, the lesion was found to display characteristic features of chorangioma, with vascular proliferation, which stained positive for CD34 and CD31. SMA and caldesmon immunohistochemical staining was also positive, highlighting the proliferation of smooth muscle throughout the neoplasm. Literature review revealed a single additional case with similar characteristics.

Myometrial morphology and myometrial physiology have been considered to be separate entities; however, observations of myometrial morphology and associated dysfunctions suggest a relationship between myometrial morphology and myometrial physiology that deserves further exploration. Although myometrial electrical activity can be monitored by electrohysterogram, the association of increased myometrial contractions with an increase in electrical activity (due to an increase in gap junctions) is typically not evaluated. Although the association of increased myometrial contractions with increase in pain can be monitored by tocometry and intrauterine pressure catheters, respectively, this is generally not done in the non-pregnant uteri. Although standard morphologic evaluations routinely include evaluation with special stains and immunohistochemistry in other organ systems, such as skeletal and cardiac muscle, these evaluations are not standard or routine for myometrium in hysterectomies. The purpose of this review is to discuss non-neoplastic myometrial histology, with consideration of the potential value of using tools to measure variations in myometrial physiology, in order to reliably correlate myometrial histology with myometrial function (and dysfunction)., (Copyright © 2022 Elsevier Inc.

Paratubal lesions comprise a large number of entities. Preoperative diagnosis is often limited to mass and location, with histology required to establish a more definitive diagnosis. The purpose of this review is to review the literature and summarize benign and malignant paratubal lesions to better understand what can arise in this area., (Copyright © 2022 Elsevier Inc.

Introduction: Metastatic neoplasms to the vulva are rare and can pose a diagnostic dilemma. As identification of the primary site can influence patient treatment and prognosis, correct diagnosis is important., Methods: PubMed was searched for applicable publications using the terms vulva, vulvar neoplasms, metastasis, and vulvar metastasis., Results: Most neoplasms metastatic to the vulva originate from other genital sources; however, extragenital primary neoplasms can also metastasize to the vulva. Vulvar metastases often occur in the setting of widespread disease., Conclusions: It is important to consider biopsy for appropriate histologic and immunohistochemical studies, as well as consider patient history to establish the primary site of metastatic lesions to the vulva, allowing optimal therapy., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2022, ASCCP.)

Objective: The aim of this second article was to complete part 1 review of nonsquamous lesions of the vulvar skin and subcutaneous tissue (Journal of Lower Genital Tract Disease, 2021), clinically and pathologically, based on the fifth edition of the World Health Organization tumor classification., Materials and Methods: A database search of PubMed and Google Scholar was performed between 1970 and 2021, using the search terms "vulva," "lower genital tract," and "non-squamous lesions." The search was limited to "human gynecological pathology." Full article texts were reviewed, and reference lists were screened for additional articles. We excluded abstracts and articles written in the non-English language., Results: An initial list of 400 articles was identified. Thirty-seven articles discussed clinicopathological features of nonsquamous lesions of the vulvar skin and subcutaneous tissue., Conclusions: Clinicopathological features of nonsquamous lesions of the vulvar skin and subcutaneous tissue as categorized by the updated World Health Organization classification are presented., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2022, ASCCP.)

Nodular hyperplasia of the Bartholin's gland is an underreported and extremely rare entity that presents as a solid lesion potentially raising concern for malignancy clinically, most solid lesions at this location are carcinomas. They may also be mistaken for a Bartholin cyst clinically. Nodular hyperplasia is rarer than carcinoma of the Bartholin gland, and hence pathologists may not be familiar with this entity, making it a pitfall in pathologic as well as a clinical diagnosis. Here we report a case originally considered a Bartholin cyst, but raising intraoperative concern due to solid elements. Histological examination of the lesion revealed nodular hyperplasia of Bartholin's gland. Recognition of this entity is important, as it is something that may be encountered by the pathologist.

Apoplectic leiomyomas-benign uterine leiomyomas with morphologic changes including hemorrhage, hypercellularity, mitotic activity, nuclear atypia, and even necrosis-can be difficult to distinguish from uterine leiomyosarcomas. Apoplectic leiomyomas have been associated with hormonal therapy; however, the relationship between apoplectic leiomyomas, hormones, and ethnicity has not received much attention in the literature. We evaluated the relationship of hormonal therapy and ethnicity in 869 women with uterine leiomyomas, 136 of which qualified as apoplectic leiomyomas.Apoplectic leiomyomas were observed in 23.3% (49/210) of women exposed to hormonal therapy compared to 13.2% (87/659) of women not exposed to hormonal therapy (p < 0.0001). Women taking ethinyl estradiol/norethindrone (Lo-Estrin), leuprolide, and medroxyprogesterone were significantly more likely to have apoplectic leiomyomas compared to women taking other hormonal therapies. Apoplectic leiomyomas were observed in 28.9% (44/152) of African-American women compared to 12.4% (79/639) of Caucasian women (p < 0.0001), and this difference remained statistically significant regardless of hormone use. Apoplectic leiomyomas were observed in 22.1% (77/349) of women ≤ 45 years of age compared to 11.3% (59/520) of women > 45 years of age (p < 0.0001), and this difference remained statistically significant regardless of hormone use.This is the largest study to date examining apoplectic leiomyomas in women on known hormonal therapy compared to women with uterine leiomyomas, but not on hormonal therapy. Information about hormonal therapy, ethnicity, and age can be helpful in the diagnostic interpretation of apoplectic leiomyoma., (© 2021.

Well-differentiated papillary mesothelioma is an uncommon benign, although potentially recurrent mesothelial lesion that occurs in the peritoneum of women over a wide age range. We recently encountered an incidental case sent for frozen section at the time of hysterectomy for endometrial carcinoma. Familiarity with this lesion will help prevent overinterpretation as a serous carcinoma.

Background: Neural tube defects can be as mild as spina bifida, to as severe as anencephaly, with only a fraction of these cases presenting as both craniorachischisis and exencephaly. Case report: The G3, P1011 mother was 25-years old, who at an estimated fetal gestational age of 17 weeks had a fetal diagnosis of anencephaly based on a sonogram, resulting in elective pregnancy termination. The female fetus had an open neural tube defect, consisting of craniorachischisis and exencephaly. No abnormalities were noted in any other organs. Conclusion: Although mostly associated with anencephaly, craniorachischisis can also be associated with exencephaly in early pregnancy.

Objectives: This article aimed to review "nonsquamous lesions of the vulvar skin and subcutaneous tissue" clinically and pathologically, based on the fifth edition of the World Health Organization tumor classification., Materials and Methods: A database search of PubMed and Google Scholar was performed between 1970 and 2021, using the search terms "vulva," "lower genital tract," and "nonsquamous lesions." The search was limited to "humans," "gynecopathology," and "dermatopathology." Full article texts were reviewed. Reference lists were screened for additional articles. We excluded articles written in the non-English language and abstracts., Results: A list of 600 articles was identified. Another screening identified 68 articles for clinicopathological features of nonsquamous lesions of the vulvar skin and subcutaneous tissue. In the first part of this review, we cover 5 major groups of nonsquamous lesions of the vulvar skin and subcutaneous tissue including (1) glandular tumors and cysts, (2) adenocarcinomas of other types, (3) germ cell tumors of the vulva, (4) neuroendocrine neoplasia, and (5) hematolymphoid hyperplasia and neoplasia. The rest of the major topics including mesenchymal tumors of the lower genital tract, melanocytic lesions, and metastasis will be discussed in the second part of this review., Conclusions: Clinicopathological features of nonsquamous lesions of the vulvar skin and subcutaneous tissue as categorized by the updated World Health Organization classification are presented., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2021, ASCCP.)

Objective: Peripherally Inserted Central Catheter (PICC) lines are an essential tool in the management of premature neonates. Pleural effusion (PLE) secondary to the leakage of alimentation into the pleural cavity is an encountered complication of central-line total parenteral nutrition (TPN) administration. Methods: We review a case of a premature neonate who suffered large, bilateral PLE after insertion of an upper extremity PICC line for TPN. Results: Pleural fluid biochemical analysis confirmed PICC line infiltration, predominantly with monocytes, low protein, high triglycerides and high glucose. These results favored TPN leakage over chylothorax. Conclusions: To our knowledge, this is the first case of bilateral PLE due to PICC complication in a neonate, which highlights the importance of chylothorax differential diagnosis, the role of autopsy, and the need for clinical precautions when providing premature neonates with high osmolarity TPN.

Superficially, invasive vulvar squamous cell carcinoma (SISCCA) (FIGO stage IA) is a rare subset of vulvar cancer defined as a single lesion measuring ≤2 cm with a depth of invasion of ≤1.0 mm. This is a retrospective study performed on 48 patients with SISCCA, surgically treated between 1981 and 2018 at the S. Anna Hospital, University of Turin, to evaluate pathological characteristics and prognosis of these tumors. Ten patients (21%) recurred: seven (14%) as SISCCA and three (7%) as deeply invasive carcinoma. One case with perineural invasion and groin node metastasis at recurrence. No patient had groin lymph node metastases at initial diagnosis. Site of SISCCA, type of surgery, status of surgical margins, and histopathological features did not differ between recurrent and non-recurrent patients. We observed a non-significant trend towards an increase of recurrences in younger women (median age: 63 years vs. 70 years, p = 0.09), while, surprisingly, smaller tumors (<12 mm) were significantly related to tumor relapse ( p = 0.03). Overall, SISCCA has a good long-term prognosis, regardless of the pathological characteristics and the type of surgical treatment. We recommend close follow-up, especially for younger patients and for small tumors, due to the possibility of recurrence or re-occurrence even after years.

It has been suggested that impaired venous drainage and endometrial vascular ectasia (EMVE), secondary to increased intramural pressure, explains abnormal bleeding in fibroid uteri. Striking EMVE with extravasated red blood cells (ecchymosis) has also been seen in uteri with grossly obvious myometrial hyperplasia (MMH), suggesting that increased intramural pressure can cause EMVE in the absence of fibroids. EMVE with MMH may explain the century old association of clinically enlarged uteri with abnormal bleeding, and this same mechanism may be operative in myopathic uteri with grossly obvious adenomyosis. EMVE with associated thrombosis, ecchymosis, and/or stromal breakdown is commonly seen in random sections of hysterectomies for bleeding. EMVE may also be associated with endothelial hyperplasia, consistent with a reaction to endothelial injury due to impaired venous drainage. This further supports the theory that EMVE bleeds when thrombosis occurs, due to Virchow's Triad (stasis, endothelial injury, and hypercoagulability). EMVE may be "the lesion for which surgery was performed" in hysterectomies with otherwise unexplained bleeding., (Copyright © 2021 Elsevier Inc. All rights reserved.)

We investigatd the influence of do-not-resuscitate (DNR) status on mortality of hospital inpatients who died of COVID-19. This is a retrospective, observational cohort study of all patients admitted to two New Jersey hospitals between March 15 and May 15, 2020, who had, or developed, COVID-19 (1270 patients). Of these, 640 patients died (570 [89.1%] with and 70 [10.9%] without a DNR order at the time of admission) and 630 survived (180 [28.6%] with and 450 [71.4%] without a DNR order when admitted). Among the 120 patients without COVID-19 who died during this interval, 110 (91.7%) had a DNR order when admitted. Deceased positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patients were significantly more likely to have a DNR order on admission compared with recovered positive SARS-CoV-2 patients (P < 0.05), similar to those who tested negative for SARS-CoV-2. COVID-19 DNR patients had a higher mortality compared with COVID-19 non-DNR patients (log rank P < 0.001). DNR patients had a significantly increased hazard ratio of dying (HR 2.2 [1.5-3.2], P < 0.001) compared with non-DNR patients, a finding that remained significant in the multivariate model. The risk of death from COVID-19 was significantly influenced by the patients' DNR status., Competing Interests: Conflict of Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Inc.

Objective: The aim of the study was to describe the features required for diagnosis of differentiated vulvar intraepithelial neoplasia (dVIN) and vulvar aberrant maturation (VAM)., Materials and Methods: The International Society of the Study of Vulvovaginal Diseases tasked the difficult pathologic diagnoses committee to develop consensus recommendations for clinicopathologic diagnosis of vulvar lichen planus, lichen sclerosus, and dVIN. The dVIN subgroup reviewed the literature and formulated diagnostic criteria that were reviewed by the committee and then approved by the International Society of the Study of Vulvovaginal Diseases membership., Results: Differentiated vulvar intraepithelial neoplasia is the immediate precursor of human papillomavirus (HPV)-independent vulvar squamous cell carcinoma and shows a spectrum of clinical and microscopic appearances, some overlapping with HPV-related neoplasia. The histopathologic definition of dVIN is basal atypia combined with negative or nonblock-positive p16 and basal overexpressed, aberrant negative, or wild-type p53. The most common pattern of dVIN is keratinizing with acanthosis, aberrant rete ridge pattern, and premature maturation. The morphologic spectrum of keratinizing dVIN includes hypertrophic, atrophic, acantholytic, and subtle forms. A few dVIN cases are nonkeratinizing, with basaloid cells replacing more than 60% of epithelium. Vulvar aberrant maturation is an umbrella term for lesions with aberrant maturation that arise out of lichenoid dermatitis and lack the basal atypia required for dVIN., Conclusions: Evaluation of women at risk for dVIN and VAM requires a collaborative approach by clinicians and pathologists experienced in vulvar disorders. Close surveillance of women with lichen sclerosus and use of these recommendations may assist in prevention of HPV-independent squamous cell carcinoma through detection and treatment of dVIN and VAM., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2020 The Author(s).

The terminology and diagnostic criteria presently used by pathologists to report invasive placentation is inconsistent and does not reflect current knowledge of the pathogenesis of the disease or the needs of the clinical care team. A consensus panel was convened to recommend terminology and reporting elements unified across the spectrum of PAS specimens (i.e., delivered placenta, total or partial hysterectomy with or without extrauterine tissues, curetting for retained products of conception). The proposed nomenclature under the umbrella diagnosis of placenta accreta spectrum (PAS) replaces the traditional categorical terminology (placenta accreta, increta, percreta) with a descriptive grading system that parallels the guidelines endorsed by the International Federation of Gynaecology and Obstetrics (FIGO). In addition, the nomenclature for hysterectomy specimens is separated from that for delivered placentas. The goal for each element in the system of nomenclature was to provide diagnostic criteria and guidelines for expected use in clinical practice.

Purpose: To determine the effect of ruptured ectopic pregnancies on the rate of future intrauterine pregnancies. Materials and Methods: This was a retrospective study of patients at a University-affiliated hospital with a history of an ectopic pregnancy between January 1991 to December 2016. All patients that underwent a salpingectomy for a tubal ectopic pregnancy were considered for this study. Intrauterine pregnancy rates for patients with a history of a ruptured ectopic pregnancy were compared to those with non-ruptured ectopic pregnancies. Fisher's exact test was used for analysis. Results: During the study period, 77 patients met the inclusion criteria. In this cohort, 14 patients with a history of a tubal ruptured ectopic pregnancy had achieved pregnancy within 12 months, compared to 24 patients in the non-ruptured group (52% vs 48%, p  = 0.81). The rate of intrauterine pregnancies, compared to repeat ectopic pregnancy, in both the ruptured and non-ruptured group, was 71% ( p  > 0.99). Conclusion(s): Ruptured ectopic pregnancies did not adversely affect the rate of intrauterine pregnancy within 12 months of rupture when compared to non-ruptured ectopic pregnancies.

Endometrioid type of endometrial carcinoma is the most common form of uterine malignancy. The majority of patients in the developed world present with the low-grade, low-stage type of this malignancy. The current treatment of early-stage endometrioid carcinoma provides most patients with a favorable outcome. One of the important factors that determine the outcome of early-stage endometrial carcinoma is the involvement of cervical stroma. One of the very rare forms of cervical stromal involvement by endometrioid carcinoma is termed "adenoma malignum type" invasion due to its similarity to the infamously deceptive type of cervical adenocarcinoma called adenoma malignum. Since adenoma malignum is often discovered incidentally, finding adenoma malignum type of myoinvasion may deceive a pathologist to diagnose the simultaneous presence of endometrial carcinoma and adenoma malignum in the same patient as 2 separate entities. Also, this type of myoinvasion may be missed altogether for its subtle nature. In this article, we report a case of low-grade, low-stage endometrioid carcinoma with adenoma malignum type of myoinvasion. We have pointed out the subtle nature of this lesion and the important features to remember to successfully identify it.

This study describes the pathology and clinical information on 20 placentas whose mother tested positive for the novel Coronovirus (2019-nCoV) cases. Ten of the 20 cases showed some evidence of fetal vascular malperfusion or fetal vascular thrombosis. The significance of these findings is unclear and needs further study.

Objective: This review aims to summarize the currently available human papillomavirus (HPV) testing methods for precancerous cervical intraepithelial lesions., Materials and Methods: A literature search of PubMed using key words "high-risk HPV, precancerous cervical intraepithelial lesions, FDA-approved HPV tests, p16 IHC, Ki 67 IHC, fluorescent in situ hybridization for HPV, Pap smear, HPV vaccines, HPV tests using self-collected samples, and next-generation sequencing" was performed between January 1 and June 14, 2019. The package inserts of the Food and Drug Administration-approved HPV tests were obtained from the companies' Web sites., Results: Multiple morphology-based, immunohistochemical staining and nucleic acid HPV tests were reviewed, including the material required, methodologies, result interpretations, as well as their advantages, limitations, and futures. The structure of HPV and its natural history of infection and transmission were touched on as well for a better understanding of these testing methods., Conclusions: Human papillomavirus tests are a critical component for cervical cancer screening, and understanding of these tests helps test results interpretation and patients' triage.

Objectives. We recently suggested that increased intramural pressure may often explain pain and/or bleeding. Hysterectomies for bleeding tend to have outward bulges and endometrial vascular ectasia, while hysterectomies for pain tend to have deflection of pressure inward by subserosal ridges, which promote inner myometrial elastosis (IME). Study design. We analyzed causes of increased intramural pressure in 58 hysterectomies for pain and/or bleeding, excluding clinically fibroid uteri and prolapsed uteri. Postfixation photographs were used to avoid missing grossly obvious myometrial hyperplasia (MMH). Results. The most common cause of increased intramural pressure was grossly obvious MMH in 40/58 cases (69%). Other causes included clinically occult myomas (3 cases), adenomyosis (6 cases), and multifactorial causes (7 cases). Hysterectomies for bleeding weighed more than hysterectomies for pain ( P = .035). Hysterectomies for pain had more IME than hysterectomies for bleeding ( P = .029). Conclusions. When subserosal ridges deflect pressure inward, bulky MMH may cause pelvic pain and IME, but when they do not, bulkier MMH in heavier uteri may lead to both outward bulges and abnormal bleeding from endometrial vascular ectasia.

Brenner tumors arise from ovarian epithelium, accounting for approximately 5% of benign ovarian epithelial tumors. The World Health Organization classification groups them into benign, borderline, and malignant on the basis of proliferation and invasiveness, and borderline Brenner tumor is defined as "displaying epithelial proliferation beyond that seen in benign Brenner's tumor, but lacking stromal invasion." Borderline Brenner tumors are rare. Fewer than 60 cases have been reported. The more recent articles mostly focus on pathogenesis. We reviewed the literature on borderline Brenner tumor and have summarized the clinical and pathologic findings, as well as the treatment, differential diagnoses, and recent advances in histogenesis and molecular pathogenesis.

Objectives: The aim of the study was to review uncommon foreskin dermatopathology conditions clinically and pathologically., Methods: A database search of PubMed and Google Scholar were extracted between March 1, 2009, and March 1, 2019, using the search terms "foreskin," "prepuce," "penis," "pathology," "dermatology," and "rare." The search was limited to "humans" and "dermatopathology." Full article texts were reviewed. Reference lists were screened for additional articles. Patient details (diagnosis, dermatopathology, treatment, and follow-up if available) were extracted. We excluded articles written in the non-English language, unusual variants of common conditions, and cases of common dermatologic conditions., Results: A list of 369 articles was identified and another screening identified 30 articles for rare foreskin pathologies. Those are divided into categories based on the following etiologies: (a) benign, including congenital (e.g., aposthia), infectious (graft versus host disease and histoplasma), autoimmune (Crohn's disease and pyoderma gangrenosum), and benign neoplasms (neurofibroma, apocrine hidrocystoma, verruciform xanthoma, porokeratosis, penile cutaneous horn, localized amyloidosis) and (b) malignancies, including primary (myeloid sarcoma, basal cell carcinoma, Kaposi's sarcoma, mucosal-associated lymphoid tissue lymphoma), and metastasis., Conclusions: We reviewed and discussed unusual benign and malignant dermatopathology conditions that can affect the foreskin.
