Fetal teratomas: antenatal diagnosis and clinical management.

Four cases of fetal teratomas arising from the sacrococcygeal and oropharyngeal areas are reported. The diagnosis, method of management, and grade of tumor are compared with previous experience in the literature. Pharyngeal lesions carry a worse prognosis for survival compared to the more common sacrococcygeal type (SCT). Atraumatic delivery and early repair of the lesion contribute to prolonged survival and lack of complications in cases of sacrococcygeal teratomas.
