Extraosseous Ewing's sarcoma
Abstract
Extraosseous Ewing's sarcoma is an undifferentiated round-cell sarcoma that is indistinguishable histologically from Ewing's sarcoma of bone. Despite this similarity, it has been accepted as a distinct clinicopathologic entity. The authors describe a 53-year-old man who presented with extraosseous Ewing's sarcoma of the left subcostal chest wall. The lesion was demonstrated by radiography and computed tomography and confirmed by pathological examination.
