We report a case of neoplasm of the urinary bladder with pseudosarcomatous stromal differentiation. Heterologous carcinosarcomas are extremly rare malignant neoplasms (seventy-eight cases have been previonsly described). This is a case of carcinoma containing numerous osteoclast type giant cells that stained for vinmentin and acid phosphatose and were negative for cytokeratin and lysozyme.
