Congenital intraocular teratoma associated with eyelid coloboma.

Purpose: To describe the first case of intraocular teratoma associated with eyelid coloboma and the second reported case of intraocular teratoma.
Design: Interventional case report.
Methods: A left intraocular tumor was surgically resected from a 2-day-old female with an associated lower eyelid coloboma.
Results: Pathologic evaluation revealed a completely intraocular tumor comprising derivatives of all three germ cell layers giving a diagnosis of intraocular teratoma. The eyelid coloboma was repaired, and a scleral-wrapped hydoxyapatite-integrated orbital implant was placed.
Conclusion: To our knowledge, this is the second reported instance of teratoma originating within the globe and the only reported case of teratoma associated with eyelid coloboma. Although exceedingly rare, intraocular teratoma should be added to the differential diagnosis of congenital intraocular tumors.
