[Wegener's granulomatosis with urethral-penile location. Apropos of a case].

The authors report a case of Wegener granulomatosis presenting as a necrotizing urethral tumor in a 44 year-old man. Involvement of the urethra by Wegener granulomatosis in unusual which explains the delay in diagnosis particularly when the urethral localization is isolated. The prognosis is severe despite urinary diversion and appropriate therapy. Five cases from the literature are reviewed. Prednisone and cyclophosphamide therapy for Wegener granulomatosis now gives dramatic results, but an urethral localization could occur in the subsequent course of the disease with the same severe prognosis.
