Carcinosarcomas (CS) are exceedingly rare in the vulva, with only 3 cases reported in the English literature, associated with squamous cell carcinoma (2) or spiradenocarcinoma (1). We first report a vulvar CS with intestinal-type mucinous adenocarcinoma associated with anaplastic pleomorphic and spindle cell carcinoma and heterologous chondro- and osteosarcomatous elements in a 62-year-old woman, who presented with a painless, slow-growing vulvar cyst for almost 2 years, that rapidly enlarged and hardened in the last 4 months forming a mass...

Squamous cell carcinoma (SCC) of the uterine cervix occasionally demonstrates a deceptive growth pattern that mimics endocervical crypt involvement by cervical intraepithelial neoplasia, grade 3 (CIN 3). Such CIN 3-like SCCs may be misinterpreted as noninvasive or minimally invasive leading to delays in diagnosis. Little is known of the factors that influence the growth patterns of cervical SCC but we suggested recently that CIN 3-like tumors might demonstrate "collective cellular invasion," which is characterized by a retained epithelial phenotype...

Microscopic, heterotopic extraovarian sex cord-stromal proliferations have only recently been reported in the literature. We describe the largest series to date, of 30 cases of microscopic, incidentally detected, heterotopic extraovarian sex cord-stromal proliferation, in women aged 25-79 yr who had undergone surgery for a range of benign and malignant gynecologic conditions. In 14 patients the foci of proliferation comprised ovarian cortical stroma, in some cases with an ovarian fibroma-like appearance. Ten cases of adenofibroma and cystadenofibroma were also identified, including 1 Brenner adenofibroma; 2 cases comprised both ovarian cortical stroma and serous cystadenofibroma; 4 cases showed sex cord proliferation resembling microscopic adult granulosa cell tumors...

Ovarian sex-cord stromal tumors that have between 10% and 50% granulosa cells in a prominent fibrothecomatous background have been referred to as granulosa theca cell tumors or mixed granulosa theca cell tumors. The classification and prognosis of these tumors is not clear. Most adult granulosa cell tumors of the ovary harbor a mutation in the FOXL2 gene, whereas fibromas and thecomas lack this mutation. The aim of our study was to assess the FOXL2 mutation status of ovarian granulosa theca cell tumors and to correlate the mutation status with morphologic and clinical characteristics...

The aim of this study was to examine the associations between microcystic, elongated, and fragmented (MELF) pattern and other prognostic factors and lymph node involvement, disease-free survival, and overall survival (OS) using a case-control group consisting of grade I-II endometrioid endometrial carcinoma (EEC) patients with/without lymph node involvement. The files of the patients were searched electronically for all hysterectomy specimens with a diagnosis of grade I-II EEC of the uterine body from January 1, 2008 to July 31, 2014...

Although immature teratoma of the ovary is a rare disease, its pathologic grading, especially between low-grade (grade 1) and high-grade (grade 2 or 3) immature teratomas, is important for optimal therapy and prognosis. This grading, however, is currently solely dependent on quantitation of neuroepithelial components as judged by subjective assessments. As we have recently successfully studied the maturation of vascular smooth muscle cells (SMCs) in other organs using an h-caldesmon to α-smooth muscle actin (α-SMA) ratio, we decided to use this ratio to investigate a potential link between teratoma grade and SMC maturation, in combination with Ki-67 index...

Uterine carcinosarcomas, also known as malignant-mixed mullerian tumors, are rare and highly aggressive tumors whose prognostic factors remain controversial. The stage at the time of presentation is the most important prognostic factor thus far, but little information exists on the prognostic impact of the sarcomatous component (SC) in these tumors. We reviewed 21 cases of uterine carcinosarcomas and estimated the volume of the SC in each case. This information was correlated with the stage of the tumor at presentation...

Differentiated vulvar intrapeithelial neoplasia (dVIN) is an human papillomavirus (HPV)-independent precursor of squamous cell carcinoma (SCC), and the aim of this study was to better characterize its natural history. Cases of dVIN were identified from the pathology archives. Outcomes of patients with dVIN only, without associated invasive SCC, were compared with a cohort of patients with high-grade squamous intraepithelial lesion [HSIL(VIN3)]. Eighteen patients diagnosed with dVIN with adjacent invasive SCC (SCC/dVIN) and 7 patients with dVIN only, without invasive carcinoma, were identified...

Microcystic, elongated, and fragmented (MELF) pattern invasion is a poor prognostic indicator in uterine endometrioid carcinoma, but its existence, biology, and prognostic value have not been described in ovarian endometrioid carcinoma. We evaluated cases of ovarian endometrioid carcinoma without synchronous uterine endometrioid carcinoma for MELF and other histologic features. To evaluate tumor biology, we assessed an immunohistochemical profile, including MLH1, PMS2, MSH2, MSH6, β-catenin, e-cadherin, CK19, and cyclin D1...

Endometrial polyps are benign pathologies originating as localized overgrowths of basal endometrium. Risk factors include endogenous and exogenous estrogen excess and tamoxifen (TAM) exposure. Our main objective was to investigate the role of an apoptosis-inhibiting protein, survivin, in endometrial polyps. We performed a cross-sectional, analytical study; our samples were obtained from the archives of Department of Pathology. Sixty samples were included, comprising 20 TAM polyps, 20 simple endometrial polyps, and 20 cases of simple endometrial hyperplasia without atypia not associated with TAM use...

The term "MELF-pattern myometrial invasion" (MELF pattern) denotes an unusual morphology of myometrial invasion in endometrioid carcinomas, and is associated with frequent lymphovascular invasion and lymph node metastasis. In this study, tumor cells were directly collected from a MELF pattern site, using laser microdissection. Comprehensive microarray analysis of the genes was conducted, and based on the results, expression of a metastasis progression gene, CXCR4, and its ligands CXCL14 and CXCL12, was further investigated...

Clear cell carcinoma (CCC) of the uterine cervix without prenatal diethylstilbestrol exposure is rare, and its etiology is unclear. We present a case of cervical CCC presenting as a submucosal tumor, which strongly suggests an association between cervical endometriosis and cervical CCC. A 56-year-old postmenopausal Japanese woman visited a gynecologic clinic with a complaint of watery vaginal discharge. A few atypical cells suggesting adenocarcinoma were detected in a cervical cytologic specimen. Magnetic resonance imaging revealed a cystic lesion with a solid component at the uterine cervix...

To use the biomarkers human papillomavirus (HPV) L1 and p16 to develop an algorithm that could triage the individual patient with CIN1 for the risk of progression. A total of 82 patients initially diagnosed with CIN1 at Peking University Shenzhen Hospital in China had their initial and follow-up paraffin-embedded tissue blocks immune-stained for HPV L1 capsid protein and p16. For CIN1, any staining of abnormal epithelium was considered positive. All patients were followed until they developed CIN2+ or for ≥3 years...

Endometrial carcinomas (ECs) are the most common gynecologic cancers in the western world. The impact of androgen receptor (AR) on clinicopathologic parameters of EC is not well studied. The aim of our study is to assess the role of AR expression in ECs and correlate its expression with estrogen (ER) and progesterone (PR). A retrospective review of 261 EC was conducted. H&E slides were reviewed and clinicopathologic parameters were analyzed. Immunohistochemical stains for AR, ER, and PR was performed on tissue microarray...

Malignant lymphoma is a rare form of malignancy in the uterine cervix. Most of the previously reported cases were B-cell lymphomas. We present a case of primary peripheral T-cell lymphoma, not otherwise specified, in the uterine cervix in a 49-year-old woman with a history of severe vaginal bleeding. The patient was treated with a CHOP (cyclophosphamide, adriamycin, vincristine, and prednisolone) chemotherapy regimen and 28 cycles of radiotherapy. Three months later, she presented with generalized lymphadenopathy and sudden left-eye ptosis as a complication of CNS involvement and died after 20 months from the initial disease presentation...

Grading and histologic typing of endometrial cancer in biopsy material has a direct impact on the decision to perform lymphadenectomy and/or omentectomy in many cancer centers. Endometrial biopsies are among the most common general surgical pathology specimens. Multiple studies have shown that biopsy diagnosis suffers from a lack of reproducibility. Although many biomarkers have been proposed, none have been demonstrated to improve the diagnosis in the biopsy setting. In this study, 70 biopsies with endometrial carcinoma were supplemented with a biomarker panel consisting of ER, PR, P53, and DNA ploidy...

Distinguishing hyalinized stroma from osteoid production by a heterologous osteosarcomatous component can be challenging in gynecologic tract carcinosarcomas. As heterologous components in a carcinosarcoma may have prognostic and therapeutic implications, it is important that these are recognized. This study examines interobserver reproducibility among gynecologic pathologists in the diagnosis of osteosarcomatous components, and its correlation with expression of the novel antibody SATB2 (marker of osteoblastic differentiation) in these osteosarcomatous foci...

Recently L1CAM was shown to be a promising biomarker for early-stage endometrial carcinoma (EC). As L1CAM expression was found to be related to serous ECs and areas of serous differentiation in endometrioid carcinomas, there is evidence that L1CAM-positive cancers more likely resemble type II carcinomas. Furthermore, expression of growth factor receptor HER2 has been found to be closely associated with serous ECs. We conducted a retrospective study on 142 patients in FIGO stages I and II with endometrioid EC and analyzed L1CAM and HER2 expression by double-staining immunohistochemistry...

Small cell carcinoma of the ovary, hypercalcemic type (SCCOHT), is a rare, highly lethal malignancy predominantly affecting young adult females. We report a patient with widely metastatic SCCOHT and concurrent uterine cervical pleomorphic liposarcoma. Clinical targeted next-generation sequencing was performed on both neoplasms and demonstrated hemizygous stop-gain TP53 mutations (p.R196*), and wild-type SMARCA4 in both tumors. Microarray analyses of both tumors revealed similar but not identical widespread loss of heterozygosity over most chromosomes associated with loss of chromosomal copy number in the SCCOHT and pleomorphic liposarcoma tumors, amplification of FGFR1 in both tumors, and amplification of MYC in the SCCOHT...
