[Carcinosarcoma of the urinary bladder and renal metastasis].
A 74 year-old woman developed a polypoid tumor of the bladder which was discovered by hematuria. Upon histological examination, the tumor was shown to be a carcinosarcoma with a weak epithelial composition confirmed by immunolabelling with keratin and was composed essentially of chondrosarcomatous material. Six months later, the patient developed metastases in the kidney, in the paravertebral muscles, and in the right para-ureteral lymph nodes. There are 55 cases of carcinosarcoma of the bladder described in the literature [3, 20, 22]. It is a tumor found more frequently in men than in women, between the ages of 33 to 83. The prognosis is very gloomy .70% death rate within 2 years), but it seems to be improved by radical cystectomy and adjuvant therapy.
