Diagnosis: Intra oral teratoma
Discussion:

Congenital intracranial Teratomas  occur 1 in 4ooo births.,only 10 % are in head & neck. It is a benign tumour ,but malignant changes have been reported.In utero it can cause hydraminos or foetal death.In newborn it can cause respiratory distress due to tracheal compression. Epignathus teratomas are rare congenital malformations giving rise to oropharyngeal tumors that result in life-threatening early neonatal asphyxia . Etymologically, the term “epignathus tumor” should be reserved for tumors arising from the jaw. Ehrich  classified oropharyngeal tumors according to the site of origin as episphenoid, epipalatine or epuranus, and epignathus tumors. However, the term epignathus tumor is generally applied to teratomas of the oropharyngeal cavity in neonates without specifying the site of origin . Although the tumors do not display any specific histopathological features, they do cause therapeutic problems, particularly since they are often associated with other malformations.These lesions are not familial in nature. They occur predominately in women at a ratio of 3:1, and this predominance remains unexplained . The majority of epignathus tumors have their point of attachment at the base of the skull in the posterior region of the nasopharynx, near Rathke’s pouch and the craniopharyngeal canal, on the midline. They usually involve the hard palate or sphenoid bone .
