Müllerian adenosarcoma of the uterus with pure angiosarcoma: case report.

We report a case of müllerian adenosarcoma of the uterus with benign endometrioid epithelial component and histologically pure angiosarcoma. This seemingly unique sarcomatous ingredient, among uterine and extrauterine adenosarcomas reported in the English literature, is considered to be a homologous component of the tumor. The patient, a 71-year-old woman with a several-month history of intermittent vaginal bleeding, was found at abdominal hysterectomy to have a large polypoid intrauterine tumor with superficial extension into the myometrium. The patient was treated with 6,000 rad of adjuvant radiation but died a few months after of what clinically appeared to be massive abdominal bleeding. The literature regarding uterine tumors classified as angiosarcoma or malignant hemangioendothelioma is briefly reviewed.
