There are no widely accepted pathologic criteria for reporting endometrial samples with limited tissue and no consensus on the clinical follow-up of patients with these samples. Our study compares clinicopathologic outcomes and determines reporting consistency for these samples. This was done in 3 parts: (1) retrospective chart review of all patients with reported insufficient or scant endometrial samples from 2010 to 2013 at our center to determine repeat sampling and final pathologic diagnosis; (2) survey of gynecologists about their practice for managing patients with these samples; (3) blind review of 99 cases of previously reported scant or insufficient samples in which 4 reviewers separately reassigned cases as scant, insufficient, or diagnostic...

High-grade vulvar intraepithelial neoplasia, a precursor lesion to vulvar squamous cell carcinoma, is subdivided into 2 types, classic or usual vulvar intraepithelial neoplasia (CVIN) and differentiated vulvar intraepithelial neoplasia (DVIN). CVIN, which is a human papilloma virus (HPV)-dependent lesion, is typically distinguished from DVIN, a p53 mutation-dependent process, by its distinct histomorphologic and immunohistochemical characteristics. However, distinguishing between the 2 entities becomes challenging in cases of CVIN with superimposed inflammatory changes, especially lichen simplex chronicus (LSC)...

Metastatic tumors of the appendix are rare. Endometrial cancer tends to metastasize by directly invading neighboring structures; the lung, liver, bones, and brain are common sites of distant metastasis. Herein, we present a case of a solitary endometrial metastatic tumor in the appendiceal mucosa without serosal involvement that mimicked a primary adenocarcinoma of the appendix. The patient who had undergone a radical hysterectomy for an endometrioid adenocarcinoma 3 years earlier presented to the hospital with a history of persistent right-lower abdominal pain...

Although the spread of extragenital tumors to individual female genital tract organs, particularly the ovary, has been much studied, histologic data with regard to secondary tumors involving the whole gynecologic tract are largely lacking. Thus, the aim of the study was to investigate the pathologic and clinical features of these tumors in order to better understand their features. This is a retrospective study of 196 secondary lesions involving the gynecologic tract. The parameters studied were the primary site, its histologic type and grade, the presence of mucous production, the type of secondary involvement, defined as distant metastasis, direct extension or locoregional recurrence, and the time to metastasis...

Three types of endometriosis are described: superficial peritoneal endometriosis (SPE), ovarian endometrioma (OMA), and deep infiltrating endometriosis (DIE). The expression of somatostatin receptors (SSTR1, 2, and 5) in human endometrial tissue and its ectopic form has been previously studied and may be different in each type of endometriosis. The aim of this study was to assess the immunohistochemical expression of SSTR1, 2, and 5 in tissue samples of SPE, OMA, and DIE. We performed a retrospective analysis in the pathology department database...

Endometrial biopsy or curetting is indicated for postmenopausal women with abnormal uterine bleeding and/or thickened endometrium. Often, endometrial biopsy or curetting yields limited benign surface endometrium, which may indicate insufficient sampling. This study addresses the clinical outcome and subsequent pathologic diagnoses in postmenopausal women who received this initial diagnosis. Among a total of 370 endometrial biopsy or curetting between 2012 and 2015, 192 (52%) were diagnosed as limited benign surface endometrial epithelium...

A 53-yr-old woman who presented with elevated renal indices was discovered to have a 4.5 cm right renal mass and an incidental 9.7 cm left ovarian mass on imaging studies. She underwent a partial nephrectomy and bilateral salpingo-oophorectomy, revealing a chromophobe renal cell carcinoma and an unusual ovarian neoplasm with epithelioid cells displaying prominent signet ring cell-like morphology. Immunohistochemical analysis of the ovarian neoplasm demonstrated that the tumor cells were diffusely immunoreactive for smooth muscle markers and negative for all tested cytokeratins and epithelial membrane antigen...

Gastric-type cervical adenocarcinoma (GCA) is a human papillomavirus-unassociated, aggressive, chemorefractory tumor. Well-differentiated examples may exhibit bland morphologic appearances, which could potentially lead to misdiagnosis, particularly in limited material. We sought to characterize the morphologic features of GCA in surgical biopsy and cytology specimens. We identified patients with histologic diagnoses of GCA or minimal-deviation adenocarcinoma between 2004 and 2017. Available slides from biopsy, curettage, and cytology specimens were reviewed...

The objective of this article was to evaluate the presence of occult metastasis after comprehensive surgical staging of clear cell ovarian carcinoma (CCC) and endometrioid ovarian carcinoma (EMCA) that appeared to be confined to the ovary at time of surgery. Between 1998 to 2016, 85 patients with CCC and EMCA were identified who were comprehensively staged and felt to be stage 1 intraoperatively. Of the 85 patients who underwent surgical staging, 4 (4.7%) had omental and dense pelvic side-wall tumor adhesions...

A chemotherapy response score (CRS) system was recently described to assess the histopathologic response and prognosis of patients with tubo-ovarian high-grade serous carcinoma (HGSC) receiving neoadjuvant chemotherapy. The current study was performed as an independent assessment of this CRS system. We retrospectively identified advanced stage HGSC patients who received neoadjuvant chemotherapy and underwent interval debulking. If available, a hemotoxylin and eosin slide from the omentum and the adnexa was selected for the study...

Sixteen adult granulosa cell tumors which had conspicuous zones of cells with pale cytoplasm imparting a resemblance to thecoma are reported. The neoplasms occurred in patients from 38 to 86 yr of age, the majority being over 55 yr of age. Ten tumors were incidental findings, the remainder being associated with symptoms or signs related to an adnexal mass. All the tumors were unilateral, typically small, usually under 5 cm, with only 3 being larger. With 1 exception they were uniformly solid and were typically entirely or focally yellow on sectioning...

Mammary analog secretory carcinoma is a primary salivary gland neoplasm with histologic, immunophenotypic, and molecular features identical to those of secretory carcinoma of the breast. Similar neoplasms have now been reported to occur in various nonmammary sites including the parotid gland, submandibular gland, sinuses, lip, skin, thyroid gland, and lung. We report, to our knowledge, the first example of a primary vulvar neoplasm with pathologic features identical to secretory carcinoma of the breast and an ETV6-NTRK3 fusion...

The preoperative diagnosis of primary ovarian pregnancy (POP) remains elusive and the final diagnosis relies heavily on histologic findings. The diagnostic criteria for POP, established in 1878 by Spiegelberg, are based primarily on the identification of an embryonic sac within the ovary and the localization of conception products therein. However, these diagnostic criteria may be overly strict, which may not only significantly underestimate the prevalence of POP, but also potentially mislead patient management...

Standardized terminology has proven benefits in cancer reporting; in contrast, reporting of benign diagnoses in endometrial biopsy currently lacks such standardization. Unification and update on the lexicon can provide the structure and consistency needed for optimal patient care and quality assurance purposes. The Special Interest Group in Gynecologic Pathology of the Canadian Association of Pathologists-Association Canadienne des Pathologistes (CAP-ACP) embarked in an initiative to address the current need for consensus terminology in benign endometrial biopsy pathology reporting...

We report 2 sex cord-stromal tumors with distinct components of fibroma and steroid cell tumor; one case was of ovarian and the other of extraovarian origin. In the ovarian tumor, there were discrete areas of fibroma and steroid cell tumor, not otherwise specified. The extraovarian case involved the pelvic soft tissues and comprised a cellular fibroma with subsequent recurrence 7 yr later as a steroid cell tumor, not otherwise specified. In both cases, aggregates of luteinized cells were present within the fibromatous component, raising the possibility that the steroid cell tumor arose from neoplastic transformation of these cells...

Seven cases of actinomycotic endometritis were identified among 28,906 endometrial biopsies performed in the last 10 yr. The patients' ages ranged from 44 to 85 yr old. An intrauterine device was in place from 7 to 44 yr. The reasons to perform the biopsies included abnormal uterine bleeding, malodor, prolapse, pelvic inflammatory disease, and suspicion of metastatic uterine sarcoma. Definitive identification of Actinomyces israelii by culture was obtained in 1 case only. Gram, Gomori methenamine silver, and Fite stains were useful in the differential diagnosis with pseudoactinomycotic granules, Nocardia, fungi, and other bacteria...

Wilms tumor (WT) is an uncommon malignant neoplasm that occurs predominantly in the kidney of pediatric patients; its extrarenal counterpart is exceedingly rare. We present the case of an adult female diagnosed with uterine WT. Following hysterectomy due to a uterine mass, histopathologic examination demonstrated a triphasic malignancy composed of epithelial, stromal, and blastemal elements. The characteristic morphologic features, which were supported by immunohistochemical analysis, were diagnostic of WT of the uterus...
