[Clinical course of Wegener's granulomatosis].

Granulomatous necrosing ulcerations in the upper respiratory tract, a generalized arteritis developing lung infarcts, and a focal glomerulonephritis in this sequence characterize the classic progression of Wegener's granulomatosis (WG). Two cases of this rarely observed disease are being reviewed, comparing the typical course of illness with a non-typical form hard to diagnose. On the basis of these cases, considering the available publications, the clinical-roentgenological peculiarities, autoptical findings, and therapeutical possibilities of this usually fatal WG are set forth. Ulcerations of the mucous membrane of the nose and oral cavity or chronic sinusitis, haemoptysis with melted round foci of the lung, which can be roentgenologically proved, as well as increasing pulmonary insufficiency, proteinuria, and haematuria with subsequent renal failure are signs and symptoms of WG. Problems of diagnosis are discussed and difficulties in diagnosing are put forward. Histological confirmation in the early phase of the illness is desirable.
