Tracheobronchopathia osteochondroplastica: rare but not to be forgotten

Abstract

We report a case of a 59‐year‐old male with a one‐month history of pleuritic chest pain who was diagnosed with tracheobronchopathia osteochondroplastica (TO). TO is a rare benign condition characterized by protruding submucosal nodules into the tracheobronchial lumen. The disease is generally asymptomatic, with rare cases of progressive nodularity, cough, dyspnoea, and haemoptysis. Diagnosis can be made via bronchoscopic visualization of bony and cartilaginous nodules on tracheal walls. Although generally benign, the rarity of this condition makes diagnosis difficult even for trained pulmonologists and frequently predisposes patients to unnecessary invasive diagnostic testing and improper management of symptoms and contributing co‐morbid conditions. We present this case to increase physician and patient awareness about this disease to help improve diagnostic strategy and knowledge of disease manifestations and potential complications.
