Extraosseous Ewing\'s Sarcoma – An Unusual Tumor at Unusual Site

Ewing's sarcoma has traditionally been known to be a primary bone tumour, which might have a soft tissue extension.Soft tissue swelling that resemble Ewing's Sarcoma histologically, but has no clear bony involvement, is recognized as Extraosseous Ewing's sarcoma (EES).The sites commonly involved with EES include paravertebral spaces, pelvis, head and neck, and lower limbs; while omentum, retroperitoneum, chest wall, and skin are the other rare locations.We report a rare case of cutaneous EES presenting as an axillary and upper arm mass.
