Ann Saudi Med 27(5) September-October 2007 www.kfshrc.edu.sa/annals 378 Tracheobronchopathia osteochondroplastica (TO) is a benign disease, first described in 1855 and rather rarely since. Only a few hundred cases have been reported. Osseocartilaginous submucos sal nodules projecting into the lumen of the trachea and bronchi characterize the disease.1 The mechanism of its occurrence remains controversial. Most cases are ass ymptomatic and frequently diagnosed incidentally durs ing intubation, endoscopy or autopsy.2,3 The incidence of TO appears to be underestimated in the literature in view of the fact that it is usually benign. However, a more accurate estimate of its true prevalence may bes come available through the use of bronchoscopy and computerized tomographic scanning.
