Diagnosis

Ewing Sarcoma

Discussion

Ewing Sarcoma accounts for 5-10% of bone tumours, but is the most common malignant bone tumour in children. It has a peak incidence of 15 years, and presents with increasing pain and swelling. The long bones are usually affected in children, the femur being the commonest site. Less than 10% occur in the fibula. The main differential diagnosis is infection.
