Congenital orbital teratoma.
A case of congenital orbital teratoma is described in which there was no organized eye only microscopic evidence of ocular tissues within the disorganized teratoma. A baby boy presented at birth with a 10-x-8-cm mass extruding from the left orbit. Magnetic resonance imaging (MRI) showed a mixed cystic-solid orbital mass containing areas of calcification and deforming the bony orbit around its margins. There was no organized eye and no intracranial extension. The eye was removed with reconstruction of the eyelids. Histopathology showed representation from all three germ cell layers consistent with a teratoma. There was no organized eye, but some disorganized ocular structures within the teratoma. Follow-up has been uneventful. Neonatologists and pediatricians should be aware of the possible diagnoses in a newborn presenting with an orbital mass, so that early definitive surgery can be performed with preservation of the globe where possible.
