title: Isolated hemangioma causing gross painless hematuria in an adolescent male.
abstract: Hematuria in children is usually a benign entity, with hypercalciuria being the usual etiology; however, rarer causes also exist, including genitourinary hemangioma. Hemangioma is a benign tumor, which has a tendency to regress spontaneously by the second year of life. Involvement of the urinary tract is rare, and in patients with bladder involvement, an accompanying syndrome such as Sturge-Weber is usually found. However, there are reports of isolated bladder hemangioma in the pediatric population causing isolated gross hematuria. We report a case of bladder hemangioma causing gross painless hematuria in an otherwise healthy 14-year-old boy.
