[Cavernous hemangioma of the bladder: a case report].

A case of cavernous hemangioma of the bladder treated with transurethral resection is presented. A 67-year-old female was admitted to this department with the chief complaint of gross hematuria. At cystoscopy a gray, sessile tumor the size of a grain of rice was found at the left lateral wall. Computed tomography confirmed the observation of the cystoscopy and showed that the tumor did not invade into the muscle layer of the bladder wall. With the preoperative diagnosis of bladder tumor, transurethral resection of the tumor was carried out on March 2, 1984 and the specimen was pathologically diagnosed as cavernous hemangioma of the bladder. Sixty-one cases of bladder hemangioma including this case are reviewed briefly.
