Granulomatous prostatitis with vasculitis. A sequel to transurethral prostatic resection.

An 80-year-old patient suffering from prostatism underwent repeated transurethral prostatic resection. Histologic examination of the prostatic tissue that was removed at the time of the second operation disclosed a granuloma with fibrinoid necrosis combined with necrotizing vasculitis. Only four cases of granulomatous prostatitis and vasculitis have been reported in the literature:two were generalized vasculitis, while in the two other instances, the vasculitis was confined to the prostate. We report an additional case of granulomatous prostatitis combined with vasculitis localized in the prostate.
