[Necrotizing vasculitis in the bladder].
The necrotizing lesion that affects the small and medium-sized arteries, commonly known as polyarteritis nodosa (PAN), usually have a systemic and variable involvement. Urothelial involvement at the level of the two ureters has been rarely described. We report a case of necrotizing vasculitis localized to the bladder that had manifested clinically as gross hematuria.
