Chronic myelogenous leukemia in a child following treatment for bilateral retinoblastoma.

A 3-year-old child was incidentally found to have chronic myelogenous leukemia (CML) during an admission for a routine ophthalmic examination under anesthesia. The child had received systemic chemotherapy and focal treatment for Groups C and D retinoblastoma in the right and left eye, respectively, when she was 7 months old. CML was treated with dasatinib, and the child attained a major molecular response.
