Abstract

A malignant mixed mesodermal tumor of the bladder from 70-year-old woman is presented. Malignant mixed mesodermal tumor is a designation applied to carcinosarcoma characterized by the presence of heterologous mesenchymal elements. The tumor tends to be large, bulky, intraluminal tumors that grows rapidly and infiltrates widely. The tumor occurs predominantly in elderly men, and aggresive surgical treatment is indicated because of the poor prognosis. Histologically this neoplasm was composed of epithelial components of transitional and squamous cell carcinoma, and mesnechymal components of fibrosarcoma, chondrosarcoma, and osteogenic sarcoma.
