Successful management of fetal cervical teratoma using the EXIT procedure.

Fetal cervical teratoma is a cause of polyhydramnios, premature labor, and newborn airway obstruction. Formation of a multispecialty team and use of the EXIT procedure is essential for survival of the neonate. Without a team, there is little hope for fetal survival; mortality will be 80-100%. Early diagnosis and planning are essential. Cervical teratomas can contribute to pulmonary insufficiency and chondromalacia because of a mass effect in utero and underdevelopment of the fetal lungs.
