Tracheobronchomegaly.

Two cases of the rare condition of tracheobronchomegaly are reported. They occurred in people of completely different racial origin and residence. They showed the characteristic features of this condition—loud, rasping, prolonged, remarkably ineffective cough, abnormally wide trachea and major bronchi, laxity of the cartilaginous rings and membranous part of these airways demonstrable on straight chest radiographs and bronchoscopy and confirmed at bronchography.
