Childhood Ewing Sarcoma
Ewing sarcoma is a cancerous (malignant) tumor which occurs primarily in the bone but can also be found in soft tissues. Ewing sarcoma can occur in any bone, but is most often found in the extremities and can involve muscle and the soft tissues around the tumor site. Ewing sarcoma cells also can spread (metastasize) to other areas of the body including the bone marrow, lungs, kidneys, heart, adrenal gland and other soft tissues. Metastases are found in about 10 to 30 percent of all patients.

Pediatric Ewing sarcoma most often occurs between the ages of 10 and 20 and is the second most common malignant bone tumor in children and adolescents. Ewing sarcoma represents about 30 percent of all pediatric malignant bone tumors and accounts for about 2 to 3 percent of all childhood cancers. About 150 children and adolescents are diagnosed with Ewing sarcoma each year in the U.S. The number of males affected is slightly higher than the number of females.
