Diffuse infiltrating anterior retinoblastoma in a 16-year-old boy.
OBJECTIVE
To report an anterior diffuse infiltrating retinoblastoma in a teenager with a positive titer for toxocariasis.


METHODS
Clinical evaluation, enucleation and description of pathology.


RESULTS
The patient had a relatively flat, white lesion near the equator of the globe, with tumor seeding in the ciliary body, zonule and in the anterior chamber. Diffuse infiltrating retinoblastoma was suspected clinically and confirmed histopathologically after enucleation.


CONCLUSIONS
Retinoblastoma can occur in a teenager who has a positive toxocara titer. The characteristic features should suggest the diagnosis of retinoblastoma, despite the patient's age.
