Alpha-fetoprotein in ovarian teratoma with glial implants on the peritoneum

A case of ovarian teratoma with glial implants on the peritoneum associated with alpha-fetoprotein (AFP) in the blood is reported. After repeated surgical excision the AFP became negative. The AFP can also be considered as a tumor marker in case of ovarian teratoma. The literature concerning ovarian teratoma with glial implants on the peritoneum is reviewed. The pathogenesis of glial implantation on the peritoneum and the association with AFP is discussed.
