Case report: A rare case of Ewing's sarcoma and osteosarcoma at different sites 10 years apart.
Ewing's sarcoma of bone and osteosarcoma are rare tumors. A combination of high-grade osteosarcoma and Ewing's sarcoma of bone in anatomically unrelated sites is unique, especially in the absence of previous radiation or retinoblastoma. We present a patient with a rare case of Ewing's sarcoma of the scapula that showed no evidence of recurrence (after 10 years of continued followup) and who subsequently presented with a primary osteosarcoma of the femur.
