title: [Wegener's granulomatosis].
abstract: A case of an unusual development of Wegener's granulomatosis is described. A long-term immunosuppressive therapy led to intermittent involution of the process, but finally a transformation to a new disease, for present qualified as "malignant histiocytosis" was the result. The cause of the transformation and the differentiation from other necrotising granulomas are discussed.
