Pulmonary tuberculosis occurred in patient with Tracheobronchopathia Osteochondroplastica / 고신대학교의과대학학술지

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.

A Case of Tracheobronchopathia Osteochondroplastica / 대한이비인후과학회지

Tracheobronchopathia Osteochondroplastica (TO) is a rare disease of the trachea characterized by the development of submucosal cartilaginous and bony nodules. The nodules are usually located at the anterior and lateral walls and sometims on the posterior membranous wall. Clinically, the manifestations of TO vary from the incidentally detected asymptomatic to life threatening diseases with airway obstruction. Bronchoscopy is a useful diagnostic tool and radiographic studies also play an important role in the diagnosis of TO. The treatment of TO is reserved for the symptomatic lesion with severe airway narrowing and the prevention of recurrent respiratory infections.
