Ewing sarcoma (health)


A type of bone tumor that occurs in children and adolescents, most often in the large bones of the arms and legs and the flat bones of the pelvis, spine and ribs. The tumor is caused by a chromosome abnormality, called a translocation (an exchange of material), most commonly between chromosomes 11 and 22 that occurs by chance alone in a single cell which divides to form the malignant clone (colony) of cells.
