title: Secondary ALL after Successful Treatment of Ewing's Sarcoma: A Case Report.
abstract: Treatment with intensification of chemotherapy using alkylating agents and Topoisomerase II inhibitors and radiotherapy has improved the outcome of patients with solid tumors such as Ewing's sarcoma. However, there are several reports of secondary malignancy following treatment of these tumors. In this article, we describe a 12 years old girl with ALL who had Ewing's sarcoma when she was 8 years old and underwent successful treatment but after two and half years at 12 years old, she came back with pallor and muscular pain.
