[Bone repair with rib graft in a patient with Ewing sarcoma of the pelvis].

Ewing sarcoma is one of the two most common bone tumors in childhood and adolescence. More than half of cases occur in the second decade of life. Ewing sarcoma is rare in adults over 30 years old. Men prevail among patients (ratio approximately 1.5:1). Ewing sarcoma is rare in children of black and Asian races. Ewing sarcoma usually occurs in metaphysis or diaphysis of long bones of extremities. Lesions of pelvic bones, ribs and shoulder blades are less common. The most common foci of metastasis are lungs, bones and bone marrow. The authors describe a 12-year-old girl with Ewing sarcoma of pelvic bones. Chemotherapeutic treatment and surgical stage with simultaneous pubic bone repair with costal graft are described.
