Extra Skeletal Ewing Sarcoma of the Abdominal Wall: Case Report

1. Abstract
Ewing sarcoma is most commonly a bone tumour which has usually extended into the soft tissues at the time of diagnosis. Exceptionally, this tumor may have extraskeletal origins which represents one kind of rare malignant tumour, most often misdiagnosed preoperatively. The diagnosis is established mainly on histology since clinical or imaging findings are non-specific.
