Malignant mixed mesodermal tumor of the ovary

Abstract

Mixed mesenchymal and epithelial tumors are highly malignant neoplasms most commonly found in the uterus. Rarely, histologically identical tumors occur in the ovary. We report a 70-yr-old woman with a malignant mixed Müllerian tumor of the ovary. The tumor contained heterologous foci of immature cartilage and striated muscle, in addition to carcinosarcomatous areas. Postoperative chemotherapy was administered, but she died within 5 mth with recurrent and metastatic tumor. A review of the literature concerning extrauterine malignant mixed Müllerian tumors is added.
