title: Extraovarian teratoma with peritoneal gliomatosis.
abstract: A 25 year old woman underwent removal of a large, incidentally discovered cul de sac teratoma. It was solid but histologically mature and had given rise to multiple peritoneal implants of mature glial tissue. She was alive without evidence of disease 57 months later. This tumor appears to represent the extraovarian counterpart of previously reported ovarian teratomas with peritoneal gliomatosis.
