Abstract
Extraskeletal Ewing Sarcoma is a rare tumor of the soft tissues. Primary Ewing Sarcoma of the lung is an exceedingly uncommon variant of Extraskeletal Ewing Sarcoma, with only a small number of cases reported in the literature. We present a case of a 43-year-old woman who presented with a locally invasive mass of the right lung, biopsy-proven to be Ewing Sarcoma.
