Abstract

Tracheobronchopathia osteochondroplastica (TO) is a rare benign disease of unknown etiology characterized by accumulation of calcium phosphate in the submucosa of large airways and benign proliferation of bone and cartilage resulting in nodular formation. We report a case of tracheobronchopathia osteochondroplastica diagnosed by Endobronchial ultrasonography in a 56-year-old man. Chest Computed Tomography revealed thickening of tracheal and bronchial wall, and multiple nodules through whole trachea. Endobronchial ultrasonography showed numerous submucosal nodules with hetero-echogenecity in the third and fourth layers. Histopathological examination revealed nonspecific bronchitis with squamous metaplasia and metaplastic ossification. We confirmed tracheobronchopathia osteochondroplastica. The patient's symptoms were successfully treated with antibiotics and oxygen supplyment. endobronchial ultrasonography can helpful diagnosis in tracheobronchopathia osteochondroplastica.
