[Osteoplastic tracheopathy].

The authors related a case of high osteoplasic tracheopathy in a women, 79 years old. The semiology and the different etiopathogenic theories are reviewed. The affection is characterized by the presence in the tracheal sub-mucosa or sometimes the bronchial sub-mucosa of cartilagenous and often bony spaces, which cuases the stenosis of the respiratory lumen. In this related case, the lesions are situated at the level of a tracheal segment compressed by an important goitre. It seems to be caused by a local metaplasia induced by the compression.
