Atypical endometriosis (A-EMS), defined by cytologic atypia and/or crowded glands resembling endometrial intraepithelial neoplasia, remains poorly understood. We aimed to refine the morphologic, immunohistochemical, and molecular features o…

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…

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…

When classifying cellular uterine mesenchymal neoplasms, histological distinction of endometrial stromal from smooth muscle neoplasms can be difficult. The only widely established marker of endometrial stromal differentiation, CD10, has mar…

Patients with low-stage, low-grade endometrial adenocarcinomas have a favorable prognosis; however, a subset has a risk of recurrence and death. We were interested in evaluating patterns of myometrial invasion and correlating them with clin…

Endometriosis is a common gynecologic disorder characterized by ectopic endometrium associated with pelvic pain and infertility. The pathogenesis of endometriosis is unclear, and several genetic, endocrine, immune, and environmental agents …

The epithelial cells of ovarian mucinous carcinomas may sometimes appear similar to those of gastrointestinal or endocervical mucinous carcinomas, but most are composed of cells that do not suggest any particular derivation. We report four …
