Abstract:
Tracheobronchopathia osteochondroplastica (TO) is an unusual disorder. It mainly affects men over 50 years old and clinical manifestations are observed when obstructive or infectious complications occur. A 50-year old woman was investigated because of productive cough and 42 years old man was investigated because of haemoptysis. In two cases, at bronchoscopy, the typical picture of TO was observed. Microscopic examination of the biopsy material revealed bone formation. TO should be considered in the differential diagnosis as an unusual cause of chronic persistent cough, haemoptysis, persistent atelectasis, and recurrent segmental or lobar infection.
