Abstract

Neuroblastoma is the most common extracranial solid tumor in children. The co- occurrence of neuroblastoma and acute lymphoblastic leukemia is rare. We report a rare case of advanced-stage neuroblastoma in a 3.5-year-old girl that was accompanied by acute lymphoblastic leukemia following treatment. Her leukemia may have been due to chemotherapy (secondary leukemia) or may have been de novo.
