Congenital cervical teratoma in neonates. Case report and review

Cervical teratomas are uncommon neoplasms. Although these lesions are histologically benign they are usually large and may cause airway obstruction. Cervical teratomas are usually diagnosed at birth. In-utero diagnosis is possible by prenatal ultrasound which assists in planning early airway management and surgical intervention. Mortality is significant but prognosis is good with airway control and complete surgical excision. However, pressure injury of contiguous structures can limit resectability and adversely affect outcome. Malignant cervical teratoma with metastasis has been reported mostly arising in adults with poor outcome. We present nine cases of neonatal cervical teratoma identified at two institutions between 1984 and 1996. One patient died before surgical intervention. All others underwent resection. There was one intraoperative death and one postoperative death. The remaining six patients did well postoperatively with no significant sequelae with 3 to 14 years follow-up.
