[Wegener granulomatosis--its limiting forms and potential of diagnosis and therapy].

Apart from the description of the typical clinical symptoms of the Wegener's granulomatosis the author particularly deals with the difficulties of the establishment of the diagnosis and their differential diagnosis. In these cases it is particularly aimed at the differential diagnosis of the primary vasculitides and to the granulomatous diseases in the area of the middle part of the face. For the therapeutic approaches in every case a possibly exact diagnosis is to be demanded. It must be admonished against the fact to begin an immunological therapy already at the suspicion of a Wegener's granulomatosis. The diagnosis must be ascertained either by the proof of organ manifestations (lung, kidney) or by repeated histological confirmation of the diagnosis.
