  • Title: Nasopharyngeal teratoma. Report of a case with prenatal diagnosis and postnatal management.
    Author: Williams LJ, Yankowitz J, Robinson RA, Benda JA.
    Journal: J Reprod Med; 1997 Sep; 42(9):587-92. PubMed ID: 9336757.
    Abstract:
    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.
