title: Ewing's tumor following bilateral retinoblastoma. A case report.
abstract: Retinoblastoma is found in a hereditary and nonhereditary form. Long survivors treated for the hereditary form seem to be predisposed for developing a second primary tumor later in life. The retinoblastoma genes are supposed to be responsible for this disposition. This report describes the development of a Ewing's tumor in a nine-year-old girl, who had both eyes removed in early life for retinoblastoma.
