Systemic necrotizing vasculitis presenting as epididymitis.

Epididymitis is an uncommonly recognized complication of systemic necrotizing vasculitis. We report 2 cases in which epididymitis heralded the onset of more severe visceral organ involvement. Early biopsy of atypical epididymitis in patients with hypertension or constitutional symptoms is important if effective therapy is to be instituted before irreversible organ damage occurs.
