General Discussion
Ewing?s sarcoma is a rare bone tumor that occurs most often in adolescents. It may also arise outside of the bone in soft tissue (extraosseous Ewing?s sarcoma). Ewing?s sarcoma is related to another type of tumor known as primitive neuroectodermal tumor (PNET). Researchers have learned that both of these tumors arise from the same primitive cell and now refer to these tumors as the Ewing family of tumors (EFT). This general term encompasses Ewing?s sarcoma of bone, extraosseous Ewing?s sarcoma, primitive neuroectodermal tumor, and Askin?s tumor (a tumor of the chest wall). Ewing?s sarcoma of bone accounts for approximately 87 percent of the tumors in this family. Ewing?s sarcoma of bone most often affects the long bone of the legs (femur) and flat bones such as those found in the pelvis and chest well. Ewing?s sarcoma is an aggressive cancer that may spread (metastasize) to the lungs, other bones, and bone marrow potentially causing life-threatening complications. The exact cause of these tumors is unknown.
