[Tracheobronchopathia chondro-osteoplastica (author's transl)].

Clinical, roentgenological and histological findings in two cases of tracheobronchopathia chondroosteoplastica are described in detail. Characteristic features of this rare disorder are calcificated, cartilaginous and osseous deposits in superficially parts of tracheobronchial mucosa. The clinical picture and x-ray changes are not very characteristic. Final diagnosis is possible by bronchoscopy with histologic examination of bioptic material (excision from tracheobronchial mucosa).
