[Mixed mesodermal tumor of the ovary].
A 68-year-old woman with a malignant mixed mesodermal tumor of the ovary is reported. Her clinical course worsened rapidly and she died 3 months after admission. At autopsy, the pelvic cavity was seen to be filled with a huge tumor mass. Histologically, the tumor contained malignant epithelial and mesenchymal elements. The epithelial component was an adenosquamous carcinoma. The stromal element was comprised mainly of anaplastic, undifferentiated spindle cells. A variety of malignant mesenchymal elements were also present. They resembled rhabdomyosarcoma, liposarcoma, chondrosarcoma, fibrosarcoma, and myxosarcoma . A review of the Japanese literature concerning this tumor is also presented.
