Massive mature solid teratoma of the ovary with gliomatosis peritonei.

Abstract

Glial implants on peritoneum and omentum may occur with mature solid teratoma of the ovary (gliomatosis peritonei). The case of a 17-year-old girl is presented, who had a massive solid ovarian teratoma with glial implants on visceral peritoneum and omentum. The massive size of the tumour posed difficulty in diagnosis. CT demonstrated a large teratoma. At laparotomy, the seedlings were initially thought to be evidence of malignancy and hysterectomy was offered which was refused by the parents. Oophorectomy was performed and the benign nature of the tumour and implants was seen on histopathology. It is important to recognize the benign nature of glial seedlings in such cases to avoid unnecessary extensive surgery.
