[Sarcomatoid carcinoma of the urinary bladder in a hemodialysis patient: a case report].
The following is a case report bladder of sarcomatoid carcinoma in a Japanese 65-year old female patient treated with hemodialysis. She developed chronic renal failure due to chronic glomerulonephritis. Fifteen months after the beginning of the hemodialysis, continuous gross hematuria was noticed, and cystoscopy revealed a broad-based bladder tumor spreading from the right lateral wall to the posterior wall. The histopathologic diagnosis of the TUR-Bt specimens was sarcoma. Radical cystectomy was performed under the diagnosis clinical stage III, T3bN0M0. The post-operative histopathologic diagnosis of the tumor was sarcomatoid carcinoma, composed of nests of transitional cell carcinoma (G 3) and predominant areas of spindle cell sarcomatoid transformation. Sarcomatoid carcinoma of the bladder in a hemodialysis patient is extremely rare, and to date this may be only the second case in Japanese medical literature.
