Ewings Sarcoma Doctors Doctor

Description: Ewing's sarcoma is a sarcoma of the bone classically described under small round blue cell tumors (SRBCT). There is considerable clinical and histologic overlap between this tumor and the primitive neuroectodermal tumor (PNET). For many years, pathologists struggled to make a diagnostic distinction. Now with sophisticated molecular biological analysis, it turns out that both tumors share a common and unique chromosomal translocation. Most investigators now believe that Ewing's sarcoma and PNET are different morphological expressions of one tumor type.
