title: Wegener's granulomatosis presenting with erosive arthritis.
abstract: We describe a patient with Wegener's granulomatosis who presented with erosive arthritis. The patient's multisystem disease responded to cyclophosphamide treatment, and the erosions healed. Our findings suggest that Wegener's granulomatosis should be added to the differential diagnosis of diseases associated with erosive arthritis.
