Abstract
Hemangiomas are benign vascular tumors, rarely seen in the genitourinary tract. A 45-year old man, with a history of urethral trauma and varicosel surgery was admitted to urology department with hematuria and hard urination. Cystourethroscopy revealed 3 cm urethral stricture on the proximal urethra and urethroplasty was applied. Microscopically, periurethral fibrovascular tissue, fibrosis in striated muscle, thickening on the walls of vessels, anastomosing irregular splits and cavernous hemangiomatous forming papillary structures were revealed. Immunohistochemically the lining cells of vascular walls are CD 31 (+)-used primarily to demonstrate the presence of endothelial cells, D2-40 (-)-selectively expressed in lymphatic endothelium. We reported the lesion as ‘periurethral hemangioma'. After treatment the patient is symptom-free without any episodes of urethral bleeding. In literature only little more than 20 cases of periurethral hemangiomas have been reported. Here, we want to share this rare lesion, which can cause hematuria, hematospermia and obsructive symptoms.
