title: Bilateral retinoblastoma with de novo constitutional balanced translocation t(2;9)(q11;p11).
abstract: The case of a 6-year-old boy with bilateral retinoblastoma (RB) and apparently de novo balanced translocation t(2;9)(q11;p11) is presented. The normality of 13q14 chromosome region has been confirmed using high resolution techniques and Esterase D assay. The hypothesis that this RB might be correlated to the translocation is discussed.
