Congenital mature orbital teratoma: A case report.

Teratomas are gonadal or extragonadal neoplasms, derived from the three embryonic tissues, composed of germ cells of the neuroectoderm, mesoderm and ectoderm. Congenital orbital teratoma (OCT) commonly affects the left orbit, primarily affecting women over men at a ratio of 2:1. We present the case of a female patient of 9 days of extrauterine life with a left mature congenital orbital teratoma. The orbit and oculoplastic service performed an orbital exenteration and total resection of the tumor mass.
