Ewing Sarcoma

Ewing sarcoma is a type of tumor that forms from a certain kind of cell in bone or soft tissue. Other names for Ewing sarcoma are primitive neuroectodermal tumor, Askin tumor, and extraosseous Ewing sarcoma. Ewing tumors often occur in teenagers and young adults.

According to the National Cancer Institute, the incidence of Ewing sarcoma is approximately three cases per million per year. The incidence in patients ages 10 to 19 is between 9 and 10 cases per million, and the same analysis suggests that the incidence of Ewing sarcoma in the United States is nine times greater in Caucasians than in African Americans.

Ewing sarcoma may be found in the bones of the legs, arms, feet, hands, chest, pelvis, spine, or skull. Ewing sarcoma also may be found in the soft tissue of the trunk, arms, legs, head and neck, abdominal cavity, or other areas.
