Wegener's granulomatosis of the prostate gland.

Wegener's granulomatosis (WG) is a systemic granulomatous vasculitis affecting medium and small arteries, venules, and arterioles. The upper and lower respiratory tract and kidney are primarily involved. Patients with classic WG essentially present with upper airway and pulmonary involvement. Renal disease is common. Involvement of other organ systems is also relatively frequent, most often heart, joints, muscles, eyes, skin, and central and/or peripheral nervous system. We present a patient in whom WG was diagnosed primarily because of prostate involvement. This seems to be a rare manifestation.
