Teratoma of the tongue in a newborn1
A large teratoma of the tongue was removed from an infant 32 hours after birth. Microscopically the tumor contained elements of all three germ layers, with immature neural tissue predominating. There was no histologic evidence of malignancy. Serum markers, initially elevated, are negative two years later. Only four teratomas of the tongue that were present at birth have been reported, which we review here. No malignant teratomas of the tongue in the newborn have been reported; prognosis of teratoma of the tongue in the newborn is unknown.
