Traqueobroncopatía osteocondroplástica: a propósito de dos casos clínicos / Tracheopathia osteochondroplastica: based on two clinical cases

ABSTRACT

The tracheopathia osteochondroplastica (TO) is a benign and rare disorder, characterized by the deposit of cartilaginous tissue in the submucosa of the larynx, trachea and occasionally the bronchi. Both the etiology and pathogenesis, as well as the incidence and prevalence, of this disease are unknown. In a large series of 16888 bronchoscopies described, the incidence of TO was 11299. This is usually an incidental finding when a bronchoscopy is performed for another reason as in the cases presented. Endoscopically, a cobblestone mucosa with yellowish-white nodules protruding into the tracheal lumen and main bronchi is observed. Other symptoms have been hemoptysis and treatment-refractory cough. Despite the low prevalence of this disease, we describe two cases presented in the same hospital, diagnosed by chance when performing a fibrobroncoscopia for the study of a solitary pulmonary nodule (AU)
