Abstract
- Fetal teratomas are histologically diverse masses containing variety of tissues foreign to the anatomic site in which they reside. Sacrococcygeal teratomas are the most common and account for 50% of neonatal teratoma. Faciocervical teratomas are rare and accounts for only 5.5% of all neonatal teratoma, having an incidence of only 20,000:1 to 40,000:1 of live births. Immature teratoma was composed of poor differentiated or embryonal tissue which coexisted mature tissue and immature tissue was originated from neuroepithelium. We have experienced a large faciocervical teratoma and present this case with a brief review of literatures.
