Cystic retinoblastoma.
A grossly cystic retinoblastoma, presumably a form of the diffuse infiltrating type, mimicked uveitis in an 81/2-year-old boy. A review of 44 cases indicated that grossly (clinically) detectably cysts are rare in this neoplasm, although microcysts are relatively common. Lesions of this nature, especially if presenting with a history of trauma, as in our patient, may lead the ophthalmologist to diagnose uveitis. The diagnosis of retinoblastoma may thus be unduly delayed.
