Solitary fibrous tumor (SFT) has been rarely documented in the female genital tract. Until now, only 5 such cases have been reported in the vagina. A 40-yr-old referred to us with a history of antitubercular treatment and intra-abdominal adhesions; for which she previously underwent laparoscopic. Subsequently, she developed a vaginal mass, which appeared as a complex cyst on ultrasonogram. Histopathologic examination of the excised mass revealed a cellular spindle cell tumor with collagenous deposition in the stroma...

Currently, the indications for progestin therapy are limited to endometrioid adenocarcinoma that are International Federation of Gynecology and Obstetrics (FIGO) grade 1, FIGO stage IA, and confined to the endometrium. However, there have been attempts to broaden the indications of progestin therapy to patients with higher FIGO grades and/or with superficial myometrial invasion. We experienced a case with myoinvasive endometrioid adenocarcinoma treated with oral progestin, whose follow-up endometrial curettage specimen showed an apparent complete histologic regression; however, the final hysterectomy specimen disclosed myoinvasive endometrioid adenocarcinoma within the superficial myometrium, with absence of residual tumor in the endometrium...

Urothelial carcinoma (UC) invasive into the muscularis propria or tumors unresponsive to treatment are indications for cystectomy. In females, with the goal of achieving complete cancer eradication and for concerns of UC extension into the adjacent pelvic organs, this may also warrant resection of the gynecologic organs. This study is aimed to assess the prevalence of unanticipated gynecologic neoplasms in anterior pelvic exenteration specimens. A retrospective review of pathology reports to identify women undergoing anterior pelvic exenteration for UC was performed (N=221), and incidentally discovered gynecologic tract neoplasms were recorded...

The authors describe the clinicopathologic features of a group of endometrial polyps that exhibited large areas of infarction, to highlight the spectrum of morphologic alterations that may occur in this setting, including moderate cytologic atypia in a subset. Forty-one infarcted endometrial polyps, classified as such based on the presence therein of confluent zones of stromal necrosis and/or sharply demarcated zones of paucicellular to acellular stromal hyalinization, were assembled from multiple institutions...

Lymphoepithelioma-like carcinoma (LELC) is an uncommon variant of squamous cell carcinoma, which is histologically identical to lymphoepithelial carcinoma of the nasopharynx. LELCs have been reported at a variety of sites, including the stomach, salivary gland, thymus, cervix, endometrium, breast, skin, bladder, and lung. We report 2 LELCs of the vagina and 1 of the anal canal, the first report of LELC at the latter site. All 3 neoplasms were diffusely positive with p16 (block-type immunoreactivity) and the anal canal lesion contained high-risk human papillomavirus type 16; the 2 vaginal neoplasms underwent human papillomavirus testing but were unsuitable for analysis...

To determine if vestibulovaginal sclerosis and lichen sclerosus (LS) are 2 distinct entities. Biopsies obtained from the vagina or vulvar vestibule that contained abnormal subepithelial collagen were reviewed. Cases were categorized either as LS or vestibulovaginal sclerosis based on presence or absence of basal layer degeneration and lymphocytic infiltrate. Clinical data collected included examination findings, biopsy site and indication, previous vulvovaginal surgery, medications at time of biopsy, vulvar LS, treatment, and response...

Endometrial endometrioid carcinoma is related to estrogen excess and expression of estrogen and progesterone receptors. Epidemiological evidence suggests that exposure to elevated androgens, as in polycystic ovarian syndrome, increases the risk of endometrial cancer. Factors impacting androgen receptor (AR) expression are not well studied. Mismatch repair (MMR) deficiency due to MLH1 gene methylation is one of the most common molecular alterations in endometrial cancer, occurring in 15% to 20% of cases. MLH1 methylation can be associated with decreased expression of other genes, so we examined the effect of MMR status on AR expression...

We report 2 ovarian sex cord-stromal tumors, a luteinized adult granulosa cell tumor and a cellular fibroma, with melanin pigment. These occurred in 44 and 61-yr-old patients, respectively. As far as we are aware, melanin pigment has not been described previously in an ovarian sex cord-stromal tumor, although it has been reported in a testicular Sertoli cell tumor. We review ovarian neoplasms containing melanin pigment.

The aim was to investigate MAGE-A4 and MAGE-A1 protein expression in high-grade endometrial cancer and determine its correlation with histologic subtype, FIGO stage, presence of vascular invasion, disease free, and overall survival. Immunohistochemical staining was performed by using 77B (MAGE-A1) and 57B (MAGE-A4) monoclonal antibodies on paraffin-embedded sections from high-grade endometrial cancers diagnosed in University Hospital Split between 1998 and 2011 (n=77). Median follow-up time for survivors was 48 mo...

Extravascular migratory metastasis (EVMM), also known as pericytic mimicry or angiotropism, is a mechanism of angiocentric tumor spread that has been investigated mainly in cutaneous malignant melanoma where it has been associated with an increased risk of metastasis. In EVMM, the tumor cells spread along the external (ablumenal) aspect of vessels without breaching the endothelium, a process that is therefore distinct from the more widely recognized intraluminal invasion. Although EVMM has also been reported in a limited range of other tumor types, to our knowledge it has not been described in squamous cell carcinoma (SCC)...

Dermatofibrosarcoma protuberans (DFSP) is a low-grade fibroblastic sarcoma that tends to arise in young to middle age adults and involve the trunk and proximal extremities. Rare examples of vulvar DFSP have been reported, including myxoid, myoid, and fibrosarcomatous variants, but detection of the characteristic t(17;22)(q22;q13) that produces COL1A1-PDGFB gene fusion has not been evaluated in a large series of primary vulvar tumors. The clinical, morphologic, immunohistochemical, and molecular cytogenetic features of 11 cases were examined...

Roche cobas 4800 human papillomavirus (HPV) test is an automated real-time polymerase chain reaction-based system that allows the simultaneous detection of 14 human papillomavirus high-risk (HR-HPV) genotypes. This test is Food and Drug Administration approved since 2011 for HPV determination in liquid-based cytologic samples, but a clinically validated technique for formalin-fixed, paraffin-embedded (FFPE) tissue specimens is presently not commercially available. In our laboratory, we have developed an HPV detection procedure in FFPE tissue by cobas 4800 HPV test...

Tumor-to-tumor metastasis is a rare phenomenon defined as a to metastasis in a histologically distinct tumor. We report an unusual case of a 51-yr-old woman who presented with a cervical, bleeding lesion diagnosed as a poorly differentiated adenocarcinoma, HPV18+. Imaging studies revealed an unresectable cervical carcinoma with an associated left ovarian multicystic teratoma. A suspicious solid nodule within the teratoma was also reported. Bilateral salpingo-oophorectomy was performed before the cervical tumor was treated...

Clear cell renal cell carcinomas (CCRCC) rarely metastasizes to the gynecologic tract. In this study, we analyzed a multi-institutional data set to provide insights into the clinical, morphologic, and immunophenotypic features of this phenomenon. Seveteen metastatic CCRCC involving the gynecologic tract [ovary/fallopian tube (n=9), vulva (n=2), uterine corpus (n=3), cervix (n=2), uterine serosa (n=1)] were analyzed. Mean patient age was 62 yr (range: 45-79 yr). Most cases (15/17) presented as a recurrence 6 to 72 mo postnephrectomy, 1 case was concurrently diagnosed, and 1 case (a cervical metastasis) was diagnosed prenephrectomy...

The distinction between benign and malignant trophoblastic lesions often presents a diagnostic challenge, even in entities with defined morphologic and immunohistochemical criteria. Lesions arising from chorionic-type intermediate trophoblast, namely placental site nodule (PSN) and epithelioid trophoblastic tumor (ETT), can be distinguished by existing criteria. However, a putative intermediate lesion termed "atypical placental site nodule" (APSN) has been described in the literature but is not well-classified...

A subset of endometrial adenocarcinomas (EACs) exhibit microsatellite instability and have deficient DNA mismatch repair (dMMR). The overall aim of the study was to compare the spectrum of mutations in endometrioid-type EAC with and without dMMR by using a clinically validated next-generation sequencing assay. We retrospectively identified 19 EACs with known mismatch repair status that had undergone targeted sequencing of a panel of cancer-related genes. The mismatch repair status was ascertained by immunohistochemistry against MLH1, PMS2, MSH2, and MSH6 mismatch proteins...

p16 immunohistochemistry is recommended by the CAP-ASCCP Lower Anogenital Squamous Terminology (LAST) Standardization Project for human papillomavirus associated Lesions as an adjunct to morphologic assessment in the diagnosis of high-grade squamous intraepithelial lesion. This study evaluates the performance of different p16 clones as compared with E6H4 (CINtec) in detecting high-grade squamous intraepithelial lesion. The 54 high-quality articles addressing the performance of p16 identified by work group 4 of the LAST Project were evaluated for: specific p16 clone, scoring method, number of cases, anatomic site, and histologic diagnoses...
