[Stridor in the neonatal period in heterotopic gastric mucosa of the hypopharynx].

A newborn girl suffered from recurrent respiratory distress and swallowing disturbances. With coughing or belching a grape-like tumor appeared in the oral cavity, which was affixed like a pendulum in the hypopharynx. Histological examination revealed a polypoid hamartoma of the hypopharyngeal wall and ectopic gastric mucosa. Various theories of embryogenesis of this very rare condition in the head and neck region are presented. No associated anomalies are reported. Complete surgical excision is curative.
