[Fetal teratoma--diagnosis and management].

: Fetal and neonatal teratoma is rare, but it is the most common tumor of the fetus and meonate. We report seven cases with fetal sacrococcygeal teratoma and two cases with craniocervical teratoma. The diagnosis, further management of pregnancy and birth are described and compared with recent literature. While craniocervical teratoma is associated with very poor prognosis, there are sacrococcygeal teratoma with good survival rate and postoperative good functional results. Very important is prolongation of pregnancy near to term.
