Abstract

Ureteral cavernous hemangiomas are an extremely rare, benign tumor. Most cavernous hemangiomas of ureter are diagnosed postoperatively by pathologic examination. A 39-year-old female patient presented with a bladder mass found incidentally by abdominal ultrasound. The patient underwent computed tomography, urine cytology, and cystoscopy. Cystoscopy showed 2 masses protruding from the right ureteral orifice. The ureteral mass was resected endoscopically. The patient was finally diagnosed with cavernous hemangioma in the right ureter. Here we report this case of a ureteral cavernous hemangioma and review the literature.

(C) The surface of the mass is lined with normal urothelium. There are numerous cystically dilated cavernous vascular structures in the lamina propria (H&E, ×40).
