[Unusual generalized granulomatosis. Two case reports (author's transl)].

Report about two cases of unusual generalized granulomatosis in males, with multiple lymphomas and involvement of internal organs and brain, leading soon to death. The diagnosis was malignant histiocytosis and disseminated eosinophilic granulomatosis. The malignant histiocytosis is differentiated from malignant fibroxantoma (malignant histiocytoma). The unusual cerebral features in the second case - diagnosed as disseminated eosinophilic granulomatosis - seem to show some relations to histiocytosis X. The problems in diagnosis of generalized granulomatosis are pointed out.
