title: Congenital orbital-intracranial teratoma with subsequent malignancy: case report.
abstract: A newborn baby had an orbital-intracranial benign teratoma radically excised with preservation of the eye. Three years later she developed recurrent proptosis, and reoperation showed an invasive orbital tumour that histologically was a malignant germ-cell neoplasm. The relationship of the two tumours is discussed. Malignant change in a benign orbital-intracranial teratoma of the newborn has not been previously reported.
