Abstract

Angiosarcoma is a high-grade vascular tumor arising from endothelial cells of blood vessels. It represents less than 1% of the mesenchymal tumors. Uterine angiosarcoma is an extremely rare tumor with less than 25 cases reported in the literature. It usually presents in postmenopausal women as uterine mass and rarely can arise in a leiomyoma. It is included in the group of tumors of aggressive behavior and poor prognosis. Herein, we present a case of primary uterine angiosarcoma in a 56-year-old female patient with a history of fibroids presenting with pelvic pain and weight loss. Abdominal CT scan showed a large uterine mass and enlarged pelvic lymph nodes. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed, and on histopathologic examination, it was found to be primary epithelioid angiosarcoma of the uterus. Immunohistochemical stains for CD31, keratin MAK-6, and keratin AE1/AE3 confirmed the diagnosis. In conclusion, uterine angiosarcoma should be suspected in any rapidly growing hemorrhagic uterine mass, and appropriate sampling and immunohistochemical stains should be considered.
