title: Peripheral bronchopathia osteochondroplastica.
abstract: Tracheobronchopathia osteochondroplastica refers to the abnormal presence of osseous and/or cartilaginous nodules in the submucosa of the trachea and/or bronchi. This disease presents with exophytic lesions that are covered by normal mucosa. In this study, we report the case of a 51-year-old man who complained of exertional dyspnea. Chest x-ray and computed tomography showed diffuse bilateral micronodular pulmonary infiltrate. Mucosal appearance during bronchoscopy was completely normal. Histologic examination of the biopsy taken by transbronchial lung biopsy showed discrete cartilaginous nodules in the walls of the bronchiole. According to our investigation, this presentation of peripheral bronchopathia osteochondroplastica has not been reported previously.
