title: Diffuse infiltrating retinoblastoma associated with persistent primary vitreous.
abstract: A two-and-a-half-year-old male child presented with unilateral leukocoria. Clinical examination disclosed what was believed to be a mild form of persistent hyperplastic vitreous associated with total retinal detachment and exophytic retinoblastoma. The enulceated eye contained diffuse infiltrating retinoblastoma with tumor cells involving a stalk of persistent primary vitreous without hyperplasia.
