title: [Fibroma of the bladder associated with a large diverticulum: a case report].
abstract: A 57-year-old woman was admitted with a chief complaint of difficult urination on June 7, 1993. A filling defect and a large diverticulum were revealed on the cystogram. Cystoscopy showed a tumor, obstructing the internal urethral orifice at the bladder neck and a diverticulum at the right posterior wall of the bladder. Under the preoperative diagnosis of a benign bladder tumor with a diverticulum, resection of the tumor and transvesical diverticulectomy were performed by a suprapubic approach. The resected tumor was smooth-surfaced, elastic soft and was measured 2.0 by 1.5 by 1.0 cm in size. Histologically, the tumor was diagnosed as a benign fibroma of the urinary bladder. The postoperative course was uneventful. Non-epithelial benign bladder tumors are rare. To our knowledge, this is the 18th case of bladder fibroma in the Japanese literature. The characteristics of bladder fibroma are briefly described.
