Summary
This study reports a rare case of congenital intraocular teratoma in a newborn girl. The benign tumor, composed of all three germinal layers, uniquely developed within the eye.
Area of Science:
- Ophthalmology
- Pathology
- Developmental Biology
Background:
- Congenital teratomas are rare tumors with derivatives from all three germinal layers.
- Intraocular tumors are uncommon, and teratomas typically occur in orbital locations.
Observation:
- A full-term infant presented with a large, greenish mass replacing the left eye at birth.
- The enucleated eye revealed a cystic, intraocular tumor filling the globe, with disorganized ocular structures.
Findings:
- Histopathological analysis confirmed a teratoma containing diverse tissues (glands, brain, cartilage, muscle, epithelium).
- Immunohistochemistry evaluated germinal layer derivatives and neuroectodermal elements within the disorganized eye.
Implications:
- This case highlights a unique intraocular presentation of a typically orbital benign teratoma.
- Distinguishing intraocular teratomas from ciliary body tumors like teratoid medulloepitheliomas is crucial for diagnosis and management.
