Necrotizing granulomatous vasculitis with eosinophilic infiltrates limited to the prostate. Case report and review of the literature.
A 67-year-old white man presented with recurrent bladder outlet obstruction due to allergic granulomatous prostatitis, with no evidence of asthma, allergies, or systemic vasculitis. He is currently doing well on a slowly tapering course of prednisone therapy and has had no recurrence of bladder outlet obstruction. This entity, although rare, must be promptly recognized in order that the proper studies can be performed to search for systemic vasculitis, and the appropriate therapy can be initiated to avoid further bladder outlet obstruction and loss of renal function.
