Congenital orbital teratoma: A clinicopathologic case report.

Here we report an extremely rare case of immature congenital orbital teratoma. The ultrasound scan at the 28 week of gestation revealed a massive, solid, and cystic mass in the left orbital region of the fetus. The lesion site was confirmed by magnetic resonance imaging. Based on clinical examination and imaging, the diagnosis of orbital teratoma without intracranial extension was made. Histopathological examination further confirmed the diagnosis of immature teratoma. The clinical course, radiographic, and histopathological findings of this disease were also summarized.
