Ewing's sarcoma in adults

Twenty-two adult patients, aged 18 and over, with Ewing's sarcoma of bone, were evaluated clinically and radiographically. They had clinical findings similar to younger patients with Ewing's sarcoma, except that they presented with fewer systemic symptoms. The radiographic characteristics included a preponderance of flat bone involvement (54%) over long bone involvement (36%). A soft-tissue mass was detected in only 55% of the cases. CT scans, when used, proved to be helpful in delineating a soft-tissue mass associated with the bony lesion, and in follow-up after therapy.
