Dermoid (hairy polyp) of the nasopharynx.

Dermoids or hairy polyps, the most primitive forms of teratoma are rare lesions affecting the nasopharynx. They arise during early embryogenesis, being derived from only two germinal layers, ectoderm and mesoderm and are invariably benign. They usually present at or soon after birth with signs of upper aerodigestive tract obstruction. A case of hairy polyp of nasopharynx in a neonate is reported for its rarity. The etiology of teratomas, their classification in head and neck region, clinical features, and management in neonates are discussed.
