Tracheobronchopathia Osteochondroplastica and Lung Carcinoma: A Rare Combination

Tracheobronchopathia osteochondroplastica is a rare benign idiopathic disorder of unknown cause affecting the large airways. Bronchoscopy and computed tomography (CT) of the thorax establish the diagnosis, but biopsy is confirmatory. We describe a case of tracheobronchopathia osteochondroplastica, rarely associated with lung cancer. There should be a high index of suspicion of tracheobronchopathia osteochondroplastica, especially in patients with malignancy; as it can easily be missed in a patient with lung malignancy.
