Abstract

BACKGROUND: Arteriovenous malformation (AVM) of the urinary bladder is an extremely rare benign vascular lesion. The clinical significance of bladder AVM lies in its presentation with painless hematuria and a hyperemic sessile bladder wall mass. CASE REPORT: A 47-year-old man presented with ir-ritative symptoms and hematuria. Cystoscopically the lesion appeared as an erythematous, broad-based mass obscuring the right ureteral orifice. The patient underwent cystoprostatectomy for suspected mass lesion. His-tologically the bladder tumor was composed of numerous malformed blood vessels of various calibers with myxoid degeneration. Immunohistochemically the bland endothelial cells lining in the vessels were reactive for markers of CD31 and CD34. Ki67 index was
