Neonatal cystic choristoma in submandibular salivary gland simulating cystic hygroma.
A congenital cystic malformation occurred in the submandibular salivary gland of a neonate. The embryogenesis and differential diagnosis are discussed. Since it seems to be a product of endodermal heterotopic differentiation or entrapment of foregut epithelial rests in the submandibular gland, it is classified as a cystic choristoma.
