Abstract
Tracheobronchopathia Osteochondroplastica (TO) is a relatively rare disease characterized by the presence of ectopic cartilage and/or bone formation in the trachea or bronchi, or both. A 75-year-old man with TO associated with adenocarcinoma of the lung is reported. He had a mass in his right upper lobe. Bronchoscopic findings showed many small yellow-white nodules in the walls of the trachea and right main bronchus except for the posterior membranous portion. The biopsy specimen from a tracheal lesion showed ectopic cartilage and bony tissue under the epithelium and the specimen from the pulmonary lesion showed adenocarcinoma. TO associated with adenocarcinoma of the lung was diagnosed. For treatment of the lung cancer, resection of the right upper lobe was performed. The postoperative course was uneventful.
