title: Necrotic intraocular retinoblastoma associated with orbital cellulitis.
abstract: Orbital cellulitis associated with retinoblastoma is uncommon and is characterized by noninfectious inflammation of the periorbital structures. The underlying mechanism is thought to be necrosis of the intraocular tumor, leading to intraocular and periorbital inflammation. We report 2 retinoblastoma patients who presented with an orbital cellulitis-like picture and discuss clinical characteristics, histopathologic features, and treatment.
