Retinoblastoma is the most common intraocular malignant tumor in children. Retinoblastoma is divided two groups, hereditary and non-hereditary. Hereditary retinoblastoma is relakd to chormosomal abnormalities. By banding technique of somatic chromosome in retinoblastoma, deletion of chromosome 13q14 is found, but it has not been reported domestically. We experienced two cases of retinoblastoma with chromosome 13q14 deletion.
