Ewing Sarcoma


This family of tumors includes Ewing tumor of bone and extraosseous Ewing sarcoma. Ewing tumors usually occur in teenagers and are more common in boys and Caucasians.

Ewing Tumor of Bone

This type of tumor is found in the bones of the legs, arms, chest, trunk, back, or head. Tumors of bone can include classic Ewing sarcoma, primitive neuroectodermal tumors (PNET), and Askin tumors (PNET of the chest wall). PNET tumors develop from the same type of early cells, and share certain biochemical and genetic features. Some primitive neuroectodermal tumors develop in the brain and central nervous system (CNS-PNET), and others develop in sites outside of the brain such as the limbs, pelvis, and chest wall (peripheral PNET).

Extraosseous Ewing Sarcoma

This type of soft tissue tumor, which grows in tissues other than bone, is found in the trunk, arms, legs, head, and neck.

Possible signs of Ewing sarcoma family of tumors include swelling and pain near the tumor.

A doctor should be consulted if any of the following problems occur:

  • Pain and/or swelling, most commonly in the arms, legs, chest, back, or pelvis (area between the hips)
  • A lump (which may feel warm) in the arms, legs, chest, or pelvis
  • Fever for no known reason
  • A bone that breaks for no known reason
