Background. Tracheobronchopathia osteochondroplastica (TO) is a rare benign disease. In most reported cases, the condition was recognized as an incidental finding at autopsy. However, recently many cases have been reported due to the increased number of bronchoscopy procedures. We identified three cases (0.16%) among 1840 bronchoscopies performed during a 5-year period. In one case the diagnosis was established from the HRCT finding. Cases. The chief complaints were fever and cough in one case and hoarseness in the other. Two cases had no symptoms. Two of the 4 cases had associated malignancies, of which primary lung cancer was diagnosed in one case and laryngeal cancer was diagnosed in the other. There was luminal stenosis of the trachea in all cases. And the main-stem bronchi were affected in two cases. No treatment for TO was performed in all cases. Conclusion. TO is concluded to be a rare disease. But in treating cases with symptoms related to upper airway obstruction, it is important to consider TO as one candidate for differential diagnosis.
