title: Malignant mixed mesodermal tumor of ovary.
abstract: A case of primary malignant mixed mesodermal tumor (MMMT) of the ovary arising de novo in a post-menopausal multiparous female is reported. The tumor contained heterologous elements in the form of cartilage and fat in addition to carcinosarcomatous areas. Post-operatively, single-agent chemotherapy was administered and up to the time of reporting the patient has been alive and well. Because of the rarity of these tumors the proper treatment remains a dilemma. The differential diagnosis of MMMT of ovary and teratocarcinoma is considered, as the two are confused frequently.
