Abstract
A 24-year-old woman presented with chronic cough and noisy breathing. Chest x-ray revealed diffuse irregularity and narrowing of the tracheal lumen. Thorax computed tomography showed irregularity, stenosis, and areas of ossification throughout the trachea and both main bronchia. Flexible bronchoscopy revealed multiple nodules protruding into the tracheal lumen. Histopathology of the nodules confirmed the diagnosis of "tracheobronchopathia osteochondroplastica." Tracheobronchopathia osteochondroplastica is a rare, benign disease that is characterized by multiple cartilaginous and osseous submucosal nodules protruding through tracheal lumen and large bronchia. The etiology is still unexplained.
