title: Perinatal management of a lingual teratoma.
abstract: BACKGROUND
  Teratomas of the head and neck are rare and occur almost exclusively in neonates. Prenatal diagnosis of these tumors allows for a carefully planned delivery that maintains an open airway and potentially improves perinatal outcome. We report the perinatal management of a huge intrapharyngeal and intra-oral teratoma that had a broad connection to the base of the tongue.
  
  
  METHODS
  An anterior neck mass (5 x 5 cm) in an otherwise normal-appearing fetus was detected at 19 weeks' gestation. The mass increased in size over the next 10 weeks to 8 x 6.8 x 4.3 cm. Marked fetal head deflexion was noted along with concomitant hydramnios. The mother had spontaneous rupture of membranes with preterm labor at 29 weeks' gestation. A 1860-g male neonate was delivered by classical cesarean delivery. A tracheostomy was performed in the delivery room for ventilation after the upper airway could not be accessed by bronchoscopy. Histologic examination after surgical excision confirmed a congenital teratoma with immature neuroectodermal tissue and alpha-fetoprotein-bearing endodermal sinus tumor components with exclusively polyvesicular vitelline characteristics. The origin of the pharyngeal mass was the base of the tongue.
  
  
  CONCLUSIONS
  The prenatal diagnosis of a pharyngeal teratoma should prompt a careful delivery plan to optimize perinatal outcome.
