Ovarian teratoma with peritoneal gliomatosis.

The case report describes the clinical and pathological features of a young girl with ovarian teratoma which showed a predominance of neural tissue. The peritoneal involvement by an admixture of mature and immature glial tissue resulted in the death of the patient despite surgery and cytotoxic chemotherapy. There was an association between this tumour and the presence of carcinoembryonic antigen and alphafetoprotein in the serum and ascitic fluid.
