Problemdiagnose Morbus Wegener

Abstract

The histological findings of granulomatous vasculitis can frequently be lacking when we try to diagnose a nasal manifestation of Wegener's granulomatosis. In such a case one has to relay upon the clinical picture and laboratory data, particular by the extremly raised blood sedimentation rate. The possibility of diagnostic failure is illustrated in four cases, all looking alone Wegener's granulomatosis. The follow up over many months sevealed that the diagnosis was correct only in two cases. A therapeutic success can falsly be interpreted, as if one were treating a case of Wegener's granulomatosis. The differential diagnosis is also discussed.
