[A case of sarcomatoid carcinoma of the urinary bladder with brain metastasis: a case report]

A 69-year-old female visited our hospital with a chief complaint of macroscopic hematuria. A non-papillary broad-based tumor was found by cystoscopy. Excretory urography and computerized tomography revealed a large invasive tumor in the left wall of the urinary bladder. The histopathological diagnosis of bladder tumor obtained by transuretheral resection (TUR-Bt) was a sarcomatoid carcinoma composed of a urothelial cell carcinoma. One month after TUR-Bt, abdominal wall metastases were found. Thus total 50Gy of irradiation therapy was performed. However brain metastasis was also found and she died 3 months after TUR-Bt.
