Teratomas are malformative tumors derived from multipotent cells and composed of tissues from endodermal, mesodermal and ectodermal layers in varying proportions. The cervical location is exceptional. Through an observation of cervical teratoma in a newborn after a review of the literature, we recall the main clinical, radiological, anatomopathological and evolutionary aspects of this affection. Despite its often benign histological nature, cervical teratoma can threaten the vital prognosis of newborns, due to the respiratory distress it causes. Multidisciplinary and adapted care from childbirth is necessary to improve the prognosis.
