We report a case of a bladder hemangioma in a 30-year-old woman. She was admitted to our department with the chief complaints of gross hematuria and dysuria. Cystoscopy revealed a red sessiled tumor 5 mm in diameter on the right wall of the bladder. Transurethral resection of bladder tumor was performed on September 13, 2000. The specimen was pathologically diagnosed as cavenous hemangioma of the urinary bladder. Including our case, 85 cases of hemangioma of the bladder are reviewed in the Japanese literature.
