Most urinary bladder hemangiomas are solitary and smaller than 3 cm in diameter, affecting the dome, posterior wall, or trigone of the bladder. Although hemangiomas can occur in individuals of any age, they are seen most often in individuals under 30 years of age and are slightly more common among males (2). A hemangioma usually presents as an incidental finding during the investigation of hematuria. The most common symptom is gross hematuria, which can be accompanied by irritative urinary symptoms and abdominal pain. Urinary bladder hemangiomas occasionally coexist with cutaneous hemangioma or are associated with one of two conditions (3–5): Sturge-Weber syndrome and Klippel-Trenaunay-Weber syndrome. In young patients, endoscopic findings of a bluish, sessile mass and gross hematuria are highly suggestive of hemangioma (1). The main differential diagnoses for pigmented lesions seen on endoscopy include endometriosis, melanoma, and sarcoma (6). Imaging tests, such as ultrasound, computed tomography, and magnetic resonance imaging, are useful in defining the location and extent of a hemangioma (2). For individuals with hemangioma, the treatment is controversial. Although there are many options available, partial cystectomy is currently the most widely used treatment for hemangioma of the urinary bladder (3, 6, 7). Although hemangioma has a benign course, follow-up is mandatory in order to detect recurrence or residual disease (3, 7, 8). The purpose of this case report was to underscore the importance of early diagnosis of hemangioma of the urinary bladder and of differentiating it from malignant neoplasms, which would affect the therapeutic strategy and patient survival.
