Tracheopathia osteoplastica is a rare, benign pathologic condition chahacterized the occurrence of numerous cartilage and bony nodules within the tissue of mucosa. We report a case of tracheopathia osteoplastica that involved both larynx and trachea. The patient was 73 years old male and had hoarseness. The neck CT showed thickened and irregular wall of the trachea extending to the level of the carina with multiple calcified nodules and plaques of bony density projecting into the lumen.

Tracheopathia osteoplastica is a rare disease characterized by submucosal cartilaginous or bony projections into tracheobroncheal lumen with sparing of the posterior membranous portion of tracheobroncheal tree. The cause of this disorder is unknown. In the past, a majority of the cases were discovered incidentally at autopsy. But recently, antemortem diagnosis is increasingly reported after the introduction of computed tomography and bronchoscopy. We report a case of extensive tracheopathia osteoplastica diagnosed antemortem by computed tomography, bronchoscopic examination and biopsy.

Tracheopathia osteoplastica(TO) is a rare, clinical and pathologic benign condition of unknown cause and characterized by submucosal cartilaginous or bony projections into tracheobroncheal lumen, usually not involved posterior membranous portion of tracheobroncheal tree. We report two cases of tracheopathia osteoplastica that involved trachea and both main bronchus, diagnosed by chest CT, fiberoptic bronchoscopic biopsy.

Tracheopatbia osteoplastica is a rare disease of unknown cause and characterized by cartilaginous or bony projection into the tracheobronchial lumen, usually not involved posterior membranous portion of tracheobronchial tree. In the past, most of the cases were diagnosed incidentally at autopsy. But after the introduction of bronchoscopy and computed tomography, antemortem diagnosis was reported. Because of initial presenting symptoms were indolent and non-specific, misdiagnosis was reported frequently and correct diagnosis was delayed usually. We report two cases of tracheopatbia osteoplastica diagnosed by fiberoptic bronchoscopic biopsy.
