Discussion

Ewing sarcoma is classically a permeative (multiple small holes) lesion in the diaphysis of a long bone in a child . Only about 40% of these tumors occur in the diaphysis, however, with the remainder being metaphyseal and diametaphyseal and in flat bones. They tend to occur primarily in children and adolescents, although a significant number occur in patients in their 20s, especially in flat bones. Although they are most often permeative in appearance, they can elicit reactive new bone that can give the lesion a partially sclerotic or patchy appearance.

 

Final Diagnosis

Ewing sarcoma
