title: [Cervical tracheogenic air cyst. Apropos of 2 cases].
abstract: The authors report 2 cases of gas-containing cervical cysts. Surgical excision by cervicotomy showed that both of these well-defined cysts were attached to the right border of the cervical trachea by a blind "pseudo-pedicle" and were lined with respiratory-type epithelium. These were 2 tracheogenic cysts, analogous to bronchogenic cysts theoretically linked to an abnormality in the development of the bronchial buds during embryogenesis. These two cases were exceptional not only by virtue of their cervical site, but also the fact that they contained air and occurred in already old women.
