Tracheobronchopathia osteochondroplastica.

Tracheobronchopathia osteochondroplastica is a rare disorder characterized by the projection of ossified formations into the trachea and bronchi. Unlike most cases, which are reported because of incidential postmortem findings, our patient presented with a slowly resolving pneumonia. The diagnosis was suspected by radiographic evaluation and bronchoscopic findings, then confirmed by histopathologic studis of a tracheal biopsy specimen. Pulmonary function studies were normal, except for flow-volume loops, which provided information for diagnosis and follow-up.
