چکیده
Introduction Ewing’s sarcoma (ES) is the second most common bone tumor after osteosarcoma in children and adolescents. ES are aggressive tumors with a tendency towards recurrence following resection and pronounced proclivity toward early hematogenous metastases to lungs and bone. No hereditary or congenital syndromes, environmental or known risk factors have been associated with the occurrence of ES. In 90% of cases, Ewing’s sarcoma family tumor (ESFT) cells harbor the translocation t(11;22) (q24;q12), and in the remaining 10% the variant translocation is t(21;12)(22;12).
