Malignant germ cell tumor of the corpus uteri

Malignant germ cell tumor of the corpus uteri is an extremely rare uterine neoplasm characterized by a typically polypoid mass deriving from primordial germ cells localized in the endometrium. Presentation is non-specific and often includes abnormal vaginal bleeding and/or discharge, a mass protruding from the vagina, abdominal and/or pelvic pain or, less commonly, difficulty passing stool and perianal pain. The malignant teratoma and yolk sac tumor histological subtypes are the most common.
