Teratoma of the cervical region is rare. It is encountered primarily in the neonate and infant. There is no apparent sex predilection. This neoplasm is usually associated with the thyroid gland and produces obstructive symptoms in the larynx, trachea, and esophagus. It is noteworthy that no infant has survived these effects unless the tumor was excised.1
In addition, there may be adverse antenatal manifestations of the tumor. Teratoma of the neck, as in many congenital anomalies, may be associated with hydramnios. Depending upon its size, it may also cause hyperextension of the neck and result in malpresentation of the fetus and dystocia.
Teratomata of the neck are composed of derivatives of the three primordial germ layers, usually with predominance of neural tissue. Most cervical teratomata have been histologically benign. However, adequate follow-up information, for the most part, is not available.1
