Endometrial clear cell carcinoma (ECCC) and clear cell adenocarcinoma of the cervix (CCAC) are uncommon gynecologic cancers that have morphologic and phenotypic features similar to ovarian clear cell carcinoma (OCCC), but the 3 entities may not be completely identical. This study identified the morphologic and phenotypic characteristics and the differences between ECCC and CCAC in Comparison to OCCC. The morphologic features of 16 ECCCs, 7 CCACs, and 22 OCCCs are described. The immunoprofiles of hepatocyte nuclear factor (HNF) 1β, napsin A, estrogen, progesterone, p53, and Ki-67 were assessed...

The replacement of the entire or extensive parts of endometrial lining by stratified squamous epithelium is a rare entity known as ichthyosis uteri. It is considered to be a benign condition but may be associated with dysplastic changes and primary squamous cell carcinoma of the endometrium. Its association with endometrial adenocarcinoma is very rare. The aetiology of this condition is not clearly understood till date. We report a case of ichthyosis uteri associated with endometrial adenocarcinoma in a 70-year-old female who presented with complaint of per-vaginal bleeding for six months and underwent hysterectomy after being diagnosed with endometrial carcinoma...

Glutamine commonly becomes a conditionally essential amino acid in cancer. Glutamine is supplied to the cell by transporters such as ASCT2 (SLC1A5), which is frequently upregulated in multiple cancers. Here we investigated the expression of ASCT2 in endometrial carcinoma, and evaluated the contribution of ASCT2 to glutamine uptake and endometrial cancer cell growth. Analysis of human gene expression data showed that ASCT2 was significantly upregulated in both endometrioid and serous subtypes of endometrial carcinoma, compared to normal, age-matched endometrium...

Clear cell carcinoma represents a distinct histologic type of müllerian carcinoma that is resistant to conventional chemotherapy. Expression of programmed cell death ligand (PD-L1) has been associated with immune evasion in numerous tumor types and may be used to identify patients who will benefit from targeted immunotherapy, particularly in the setting of mismatch repair defects. We evaluated PD-L1 expression in 23 ovarian clear cell carcinomas and 21 endometrial clear cell carcinomas, and correlated expression with mismatch repair status...

Neuroendocrine tumours are uncommon or rare at all sites in the female genital tract. The 2014 World Health Organisation (WHO) Classification of neuroendocrine tumours of the endometrium, cervix, vagina and vulva has been updated with adoption of the terms low-grade neuroendocrine tumour and high-grade neuroendocrine carcinoma. In the endometrium and cervix, high-grade neoplasms are much more prevalent than low-grade and are more common in the cervix than the corpus. In the ovary, low-grade tumours are more common than high-grade carcinomas and the term carcinoid tumour is still used in WHO 2014...

Clear cell carcinoma of the endometrium is a rare type of endometrial cancer generally associated with an aggressive clinical behavior. Here we sought to define the repertoire of somatic genetic alterations in endometrial clear cell carcinomas (ECCs) and whether ECCs could be classified into the molecular subtypes described for endometrial endometrioid and serous carcinomas. We performed a rigorous histopathological review, immunohistochemical analysis and massively parallel sequencing targeting 300 cancer-related genes of 32 pure ECCs...

Brenner tumor is a rare ovarian neoplasm that is seen in women of the fifth to sixth decade. Classified as benign, borderline, and malignant, these tumors may be associated with estrogen production, thus altering the estrogen-progesterone ratio. High estrogen stimulates the endometrium and this is responsible for producing various pathologies, namely, hyperplasia, atypia, and carcinoma. Very few case reports have been published highlighting the same. A case report is being presented here of a coexisting Brenner tumor and well-differentiated endometrial carcinoma in a 55-year-old nulliparous postmenopausal woman...

Endometrial epithelium is the presumed tissue of origin for both eutopic and endometriosis-derived clear cell and endometrioid carcinomas. We had previously hypothesized that the morphological, biological and clinical differences between these carcinomas are due to histotype-specific mutations. Although some mutations and genomic landscape features are more likely to be found in one of these histotypes, we were not able to identify a single class of mutations that was exclusively present in one histotype and not the other...

Endometrial dedifferentiated carcinoma consists of a combination of undifferentiated and differentiated carcinomas. To date, clear cell carcinoma components in endometrial dedifferentiated carcinoma have not been reported. We report the first case of endometrial dedifferentiated carcinoma with clear cell carcinoma in a 58-year-old woman. The uterine corpus was completely replaced and enlarged by a heterogeneous mass. The endometrial cut surface showed a yellowish papillary growing mass involving endometrium and deeper myometrium...

Large-cell neuroendocrine carcinoma (LCNEC) is a high-grade neuroendocrine tumor. LCNECs arising from the genital organs are highly malignant and rare, with <20 cases of LCNEC developing from the uterine endometrium reported to date. We herein present the case of a patient with LCNEC of the endometrium. The patient was a 52-year-old woman, who exhibited lower abdominal pain and rapid uterine enlargement during outpatient treatment for uterine myoma. The endometrial biopsy suggested a diagnosis of poorly differentiated carcinoma or carcinosarcoma...

Endometrial carcinoma (ECA) is frequently hormonally driven and can be treated with endocrine-based therapy, yet hormone receptor status is not routinely assessed. In particular, little is known about the significance of androgen receptor (AR) in ECA. Androgen has antiproliferative effects in the healthy endometrium and could serve a similar role to progesterone in curbing the progression of estrogen-dependent neoplasia. There may also be a subset of ECA that benefits from androgen antagonistic therapy. We herein investigate AR expression across ECA subtypes and compare its expression to estrogen receptor (ER) and progesterone receptor (PR)...

During the last decade sentinel lymph nodes biopsy has become an essential part of primary surgical treatment in a number of malignancies including breast cancer, melanoma and head-and-neck malignancies. Dye or radioactive substances are injected at the primary tumor site, followed by pre-operative and intra-operative mapping. During surgery only positive lymph nodes are being dissected instead of a complete dissection of the lymphatic basin. The advantages of sentinel lymph nodes dissection are reducing the side effects of extensive lymph nodes dissection, while maintaining high detection rates and sensitivity in identifying cases with lymphatic tumor spread...

Endometrial cancer (EC) is the estrogen-dependent gynecologic malignancy, however the molecular mechanism involved in the development and progression of EC remain unclear. The aim of this study was to investigate the role of RIZ1 in EC. Immunohistochemical analysis revealed that RIZ1was decreased in EC than in normal endometrium. Lower RIZ1 level was correlated with high-grade carcinoma (p = 0.048) and positive expression of ERα (p = 0.004). In EC cells, estrogen could down regulated the expression of RIZ1, however, ICI182,780 could up regulated the expression of RIZ1...
