Ewing sarcoma in an infant and review of the literature

Abstract

Ewing sarcoma (ES) is a rare tumor in infants and prognosis is controversial.There are no standard recommendations for treatment in such very youngpatients. Generally, radiotherapy (RT) is not a part of treatment in infantsdue to the risk of severe late side effects. In this case report, we report a7-month-old boy with diagnosis of left mastoid bone ES with lung metastasesat diagnosis, showing a rapidly fatal outcome despite aggressive systemicchemotherapy and RT without surgery.
