BOCCIA, Carlos Mario et al. Tracheobronchopathia Osteochondroplastica: Clinical Presentation mimicking Asthma. Rev. amer. med. respiratoria [online]. 2012, vol.12, n.2, pp.62-66. ISSN 1852-236X.

The tracheobronchopathia osteochondroplastica (TO) is a rare disease of unknown pathogenesis. It is characterized by multiple osteocartilaginous nodules protruding into the tracheobronchial airway lumen. Generally it is an incidental finding because its evolution is chronic and benign; when symptoms are present, they are non specific and result from the obstruction of the airway, the thickening of the tracheobronchial wall or some complication. Since it is an uncommon condition the diagnostic errors are frequent. We report a symptomatic TO case, that was misdiagnosed as asthma, and in addition the patient had chronic sinusitis and recurrent upper and lower respiratory tract infections. This case had progressive invasion of distal bronchi. We also report two other suspected cases without endoscopic confirmation.
