THREE CASES OF IMMATURE TERATOMA OF OVARY WITH DISSEMINATING METASTASES IN ABDOMINAL CAVITY

Abstract

Immature teratoma of ovary is a relatively rare tumor and has difficulty to expect its prognosis and histological maturity. Most immature teratomas are classified in the intermediate group of ovarian tumor, but there are a few cases which have much worse prognosis with wide spread metastases. We have experienced three cases of immature teratoma of ovary with disseminating metastases to the great omentum and the peritoneum. We report the clinical and pathological studies of these three cases, especially neural tissues of the primary tumors.
