A rare case of radiation-induced malignant mixed mesodermal tumor of the bladder is reported. A 78-year-old woman complained of hematuria, which originated from a polypoid tumor in the bladder 15 years after radiotherapy for squamous cell carcinoma of the uterine cervix. The bladder tumor recurred 9 months after resection and partial cystectomy then was performed. Histological findings revealed malignant mixed mesodermal tumor composed of carcinomatous and sarcomatous elements. The former element consisted mainly of transitional cell carcinoma with occasional foci of squamous metaplasia and glandular differentiation, while the latter consisted of spindle cell sarcoma showing partly cartilaginous and osseous differentiation. The histogenesis of malignant mixed mesodermal tumor of the bladder also is discussed.
