Mesonephric-like adenocarcinoma (MLA) is a rare and aggressive gynecologic malignancy that has only been recognized in the last decade. It arises in the endometrium, ovaries, and other extrauterine sites (often in association with endometri…

Clear cell carcinoma (CCC) is an uncommon malignancy accounting for ∼12% of ovarian carcinomas. Most cases arise from endometriosis, frequently an endometriotic cyst. We report a series of 6 cases where clear cell proliferations, morphologi…

Mesonephric-like adenocarcinomas (MLA) are rare neoplasms arising in the uterine corpus and ovary which have been added to the recent 2020 World Health Organization Classification of Female Genital Tumors. They have similar morphology and i…

Mesonephric-like adenocarcinoma (MLA) was introduced as a new tumor type in the endometrium and the ovary in the 2020 World Health Organization (WHO) Classification. This is a rare recently described (2016) and clinically aggressive carcino…

Microscopic sex cord proliferations are an uncommon finding, most often associated with ovarian or uterine stromal, epithelial, or mixed epithelial and stromal neoplasms. Rarely they occur in conjunction with a non-neoplastic process such a…

Microscopic sex cord proliferations are a rare incidental finding seen in association with ovarian and uterine stromal or epithelial neoplasms and more uncommonly non-neoplastic conditions such as endometriosis and adenomyosis. They may als…

Ovarian seromucinous borderline tumors (SMBT) and clear cell tumors are both closely associated with endometriosis and share, in a proportion of cases, a molecular pathway involving ARID1A mutations, but they have been rarely described in a…

Ovarian endometrioid carcinoma, more than any other type of ovarian epithelial malignancy, demonstrates a varied morphology which can cause problems in diagnosis. In tubo-ovarian tumor pathology, WT1 is a commonly used marker as it is consi…

Mullerian adenosarcoma is a biphasic neoplasm composed of benign or atypical Müllerian epithelium and a malignant mesenchymal component that is usually, but not always, of low grade. Focal architectural or cytologic atypia of the epithelial…

Mutations and other molecular events involving subunits of the SWI/SNF chromatin remodelling complex are common in a wide variety of malignancies, including those arising at various sites in the female genital tract. Endometrioid and clear …

Mesonephric-like adenocarcinomas are rare neoplasms occurring in the uterine corpus and ovary which bear a close morphologic resemblance to cervical mesonephric adenocarcinomas. They also have a similar immunophenotype and harbor similar mo…

AIMS: To report a series of benign ovarian seromucinous neoplasms, an uncommon and hitherto poorly described category of tumours included in the current 2014 World Health Organisation classification of tumours of the female reproductive org…

Müllerian adenosarcoma is an uncommon biphasic malignant tumor most often occurring in the uterine corpus and derived from native surface endometrium. We report a case of intramural uterine adenosarcoma arising in association with adenomyos…

Endometriosis is an extremely common condition and, in most cases, establishing a histological diagnosis is straightforward, although a variety of benign alterations may result in problems with interpretation. In this review, I discuss sele…

Accurate staging of cancers is an important determinant of prognosis and guides optimal patient treatment. Although the International Collaboration on Cancer Reporting recommends that endometrial cancers (including carcinosarcomas) are path…

Mesonephric adenocarcinoma most commonly arises in the cervix and is presumed to be derived from normal or hyperplastic mesonephric remnants. It is characterized by recurrent KRAS mutations and lack of PIK3CA/PTEN alterations. Adenocarcinom…

ABC genes, especially ABCB1 (ATP-binding cassette, sub-family B (MDR/TAP), member 1; Doxorubicin resistance; Multidrug resistance 1; Multidrug resistance protein 1; P-glycoprotein 1; P glycoprotein 1/ multiple drug resistance 1;P-gp) (7q21.…

Seromucinous neoplasms are a new category of ovarian epithelial tumor in the revised World Health Organization Classification of Tumours of the Female Reproductive Organs. Borderline variants are well described, but there have been few repo…

Ovarian endometrioid adenocarcinomas may have an extremely variable morphologic appearance and mimic a number of other epithelial malignancies as well as nonepithelial tumors. We report the clinicopathologic features of a small series of ov…

Primary intestinal-type glandular lesions of the vagina are rare. We report a series of 14 lesions, including 1 intestinal-type polyp without neoplastic features, 3 adenomas (2 with high-grade dysplasia), and 10 adenocarcinomas. Patients ra…

AIMS: To look for FOXL2 mutation in rare ovarian epithelial lesions showing stromal components with morphological features of adult granulosa cell tumour (AGCT). METHODS AND RESULTS: We report the 402C→G FOXL2 mutation status in five epithe…

Intravascular leiomyomatosis (IVL) is characterized by the presence of smooth muscle in venous and lymphatic spaces within the myometrium. Although the intravascular component usually consists solely of typical smooth muscle or variants of …

Endometriosis is a common condition in women of reproductive age and has a known propensity to involve abdominal wall scars. The authors report 2 cases of endometriosis presenting as mass lesions involving the abdominal wall at the site of …
