Unilateral retinal dysplasia clinically mimicking retinoblastoma.

Retinal dysplasia is a rare non-neoplastic congenital disorder characterized by aberrant differentiation of the retina with formation of abnormal tubular and rosette-like structure. Clinically, the lesion presents with leukocoria and mimics a retinoblastoma. One such case is described that occurred unilaterally in a 9-month-old boy.
