Abstract
Teratomas are perinatal neoplasias developed from primitive gonadal germ cells. There cervical location is very rare and presents any risks of diagnostic error. we report a case of an 18-year-old female patient without any pathological history received for an anterior cervical swelling that had been evolving about 12 months ago. The mass was mobile on palpation and swallowing evoking a nodular goiter both on clinical examination and neck CT scan. Lost sight, she reappeared 13 months later presenting a neck fistulization and pendulous pedicled cervical mass with a peri-pedicular oozing orifice, posing the indication of an enlarged total lumpectomy which was performed under general anesthesia. The evolution was marked by complete post-operative healing. teratomas are most often intragonadal. The cervical form of adult person is exceptional and can be confused with a thyroid tumor. That could be a source of diagnostic difficulties and therapeutic delay. cervical masses can be indicative of various types of pathology therefore we must think at all in front of this one.
