Head and neck teratomas in children.

Abstract

A retrospective review of seven patients with teratomas of the head and neck treated at out center over the past 5 years, which represented 2% of all teratomas (sacrococcygeal, ovarian, and retroperitoneal) seen over the past 20 years, was performed. After investigation to exclude associated anomalies, all but one of the children underwent surgery for removal of the tumour. All excised tumours were subjected to histopathological examination to confirm their teratomatous nature. The patients were followed up at regular intervals for up to 4 years. The patients' ages ranged from newborn to 2.5 years. There were three cervical, two oral, and two skull teratomas. The youngest patient had a cervical teratoma with respiratory compromise, requiring tracheal intubation. All but one patient (skull teratoma) had excision of the tumours with a satisfactory outcome. Histopathological examination of the excised tumours showed mature tissue from the three germinal layers in all specimens. Specific components included glandular epithelium, keratinising epithelium, and muscle fibres. Follow-up did not show any recurrence in the operated children. The three with cervical teratomas had normal levels of thyroid hormone postoperatively. Head and neck teratomas in children are mostly benign lesions amenable to curative excision. In cervical teratomas airway management takes priority.
