Tracheobronchopathia Osteochondroplastica as a Single Mass in Lingular Bronchus.

We describe a rare case of tracheobronchopathia osteochondroplastica (TBO) in a 35-year-old man who presented with recurrent chest infection and hemoptysis. Bronchoscopy and computed tomography scan revealed a single 1.5-cm hard nodular mass lesion in the lingular bronchus associated with collapse and bronchiectasis of the lingula. The patient underwent open left lingulectomy with removal of the mass. Histopathology of the lesion showed characteristic features of TBO. TBO is generally characterized by multiple nodules in the trachea or main bronchi. The presentation of TBO as a single dominant mass is rare and can be considered as a differential diagnosis for intrabronchial calcified mass lesions.
