“…The term malignant mesodermal mixed tumor [1][2][3] is conventionally used as a synonym for carcinosarcoma [4][5][6][7][8][9]. Although, in 1975 in the urological field, Koss [10] first referred to a tumor that included heterologous components, such as bone, cartilage and striated muscle, as a malignant mesodermal mixed tumor, the histogenesis was not clarified.…”

Malignant mesodermal mixed tumor comprised of epithelial and nonepithelial components is rarely encountered in the urological field. Only 6 cases of malignant mesodermal mixed tumor of the ureter have previously been reported in the literature. We recently encountered a 7th case of malignant mesodermal mixed tumor of the ureter and describe the case in detail. The etiology of malignant mesodermal mixed tumor is also discussed.

et al. 1985

View full text Add to dashboard Cite

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.
