Background:
Oral teratomas are rare entities.
Case:
A patient was referred for elevations in the maternal serum alpha-fetoprotein. On ultrasound examination, a cyst was seen protruding from the fetal mouth. Postnatally, a teratoma was found to be filling the neonate's oral cavity.
Conclusion:
This case illustrates problems in determining the etiology of head and neck masses antenatally. It also shows that teratomas can appear to regress and yield positive amniotic fluid alpha-fetoprotein and acetyl-cholinesterase. The appropriate perinatal management of this potentially devastating disorder includes preparation for establishing an airway following delivery.
