Anesthetic management of a neonatal lingual gastric duplication cyst: report of a rare case.

Gastrointestinal duplications can occur anywhere from the mouth to the anal cavity. The occurrence of a duplication cyst in the tongue of a neonate is very rare. These cysts occur due to endodermal cells that are trapped during development. Congenital lingual cystic masses are challenging entities. They usually present in the neonatal period and surgical excision is curative. We report a 10-day-old, 3-kg neonate with a gastric duplication cyst in the oral cavity with inability to close his mouth or breast feed for whom we performed subtotal excision of the cyst.
