Uterine corpus dissecting leiomyoma

Uterine corpus dissecting leiomyoma

Definition

A rare morphologic variant of uterine corpus leiomyoma. Macroscopically, it is characterized by large, fungating, and multinodular neoplasm masses arising from the uterine corpus, and extending into the broad ligament or the peritoneal cavity. Microscopically, it shows neoplastic smooth muscle cells infiltrating the myometrium. The neoplastic cells are arranged in a micronodular pattern. Hydropic changes and increased vascularity are also present.

Also known as Cotyledonoid dissecting leiomyoma, Sternberg tumor, Sternberg tumour — per MONDO
