We report a case of difficult endotracheal intubation in a patient with tracheobronchopathia osteochondroplastica. A 65-year-old man was scheduled to undergo ulnar nerve decompression and ganglion excisional biopsy under general anesthesia. During induction of general anesthesia, an endotracheal tube could not be advanced through the vocal cords due to resistance. A large number of nodules were identified below the vocal cords using a $Glidescope^{(R)}$ video-laryngoscopy, and fiberoptic bronchoscopy revealed irregular nodules on the surface of the entire trachea and the main bronchus below the vocal cords. Use of a small endotracheal tube was attempted and failed. a laryngeal mask airway (LMA $Supreme^{TM}$) rather than further intubation was successfully used to maintain the airway.

Tracheobronchopathia osteochondroplastica (TO) is a rare idiopathic tracheobronchial abnormality characterized by diffuse cartilaginous and osseous nodules protruding into the airway lumen of the trachea and bronchus. TO is easy to misdiagnose because of nonspecific symptoms and chest CT scan with pathologic biopsy is necessary for definitive diagnosis. We report two cases of patient with TO who underwent laryngomicroscopic biopsy and tracheostomy with literature review.

Tracheobronchopathia osteoplastica (TO) is a rare benign disease in which the anterior inner wall of the tracheobronchus changes because of abnormal chondrogenesis or ossification, while the posterior wall of the trachea is spared. The etiology is not clearly understood, but may relate with chronic infection, inflammation, and trauma. In some case studies, it has also been reported to be accompanied by other chronic diseases such as atrophic rhinitis and amyloidosis. However, Coexistence of TO and tuberculosis has rarely been reported, and has never been reported in Korea. Here, we report a case of a 70-year-old male patient who complained of hemoptysis and whose case was diagnosed as TO and pulmonary tuberculosis through bronchoscopy with bronchial washing and biopsy.

Tracheobronchopathia osteochondroplastica (TO) is an uncommon benign disease of an unknown etiology and it affects the cartilaginous walls of large airways. Most cases of TO have been reported to involve the lower two-thirds of the trachea and the proximal bronchi. Unlike the usual cases of TO, exclusive bronchial involvement and the formation of a solitary mass are very rare. We experienced an unusual case that had exclusive bronchial involvement and the formation of a solitary mass and this all mimicked lung malignancy. After surgical resection, we were finally able to diagnose the mass as bronchopathia osteochondroplastica.
