[Tracheobronchopathia osteochondroplastica].

Tracheobronchopathia osteochondroplastica (TO) is a rare disease of unknown etiology affecting mainly the trachea and large bronchi. It is characterized by the presence of multiple submucosal osseus and/or cartilaginous nodules. The authors report a case of 74-year-old woman in whom fiberoptic bronchoscopy, performed because of hemoptysis, revealed typical feature of TO. Besides the typical nodules protruding into the lumen of trachea and main bronchi, a small soft nodule in the larynx was found. On histological examination it was showed to be polyp with regions of inflammation and necrosis. The direct relation between such a laryngeal polyp and TO seems to be very unlikely.
