Overview

Ewing's sarcoma is the common name for primitive neuroectodermal tumor. It is a rare disease, and until recently, it had a very low long term survival rate. It is a small round-cell tumor in which cancer cells are found in the bone or in soft tissue (rarer). The most common areas in which it occurs are the pelvis, the femur, the humerus, and the ribs. James Ewing (1866-1943) first described the tumor, establishing that the disease was separate from lymphoma and other types of cancer known at that time. Ewing's sarcoma occurs most frequently in male teenagers.
