[Clinical and histomorphologic findings in Wegener's granulomatosis]

The Wegener's granulomatosis is a rare primary systemic vasculitis. It is diagnosed more frequently in the last years. Because of various manifestations (rhinitis, sinusitis, otitis, arthralgie, "red eye", neuritis, carditis) and different symptomatics the disease is misjudged over month and years. Clinical findings, problems of bronchopulmonary and histomorphological diagnostics and differential diagnosis are discussed. The prognosis is favourable in cases of early and timely diagnosis and therapy.
