title: Cervical teratoma.
abstract: Cervical teratomas are rare tumors in an unusual location. A neck mass in a newborn was excised when it enlarged disproportionately; histologically, it was a teratoma. Teratomas may occur because of an alteration in sterol chemistry; conception in this case occurred while the mother was ingesting estrogens. Retinal tissue, an unusual finding, was present in this teratoma. Symptoms in cervical teratomas are secondary to interference with deglutition and respiration. Treatment is surgical excision.
