Tracheobronchopathia osteochondroplastica concurrent with peripheral lung cancer: a case report and perioperative considerations

Tracheobronchopathia osteochondroplastica (TPO) is a rare, benign, chronic disorder of unknown etiology. It is characterized by submucosal nodules, often calcified, which predominantly affect the anterolateral aspects of the trachea and main bronchi, while sparing the posterior bronchial wall. The co-occurrence of TPO and lung cancer is exceedingly rare. This report presents a case of TPO association with early-stage lung cancer, which was managed through surgical intervention. No active treatment was undertaken for the TPO.
