Tracheobronchopathia Osteochondroplastica (TO) is a rare disease of the trachea characterized by the development of submucosal cartilaginous and bony nodules. The nodules are usually located at the anterior and lateral walls and sometims on the posterior membranous wall. Clinically, the manifestations of TO vary from the incidentally detected asymptomatic to life threatening diseases with airway obstruction. Bronchoscopy is a useful diagnostic tool and radiographic studies also play an important role in the diagnosis of TO. The treatment of TO is reserved for the symptomatic lesion with severe airway narrowing and the prevention of recurrent respiratory infections
