What is ewing s sarcoma and where is it found?
Ewing’s sarcoma / Peripheral Primitive Neuroectodermal Tumours (PNET) of bone is a type of cancer usually found in children and young adults. The peak incidence is between ages 10 and 20, it is less common in children under 5 or in adults over 30. Ewing’s s can occur in any bone in the body; the most common sites are the pelvis, thigh, lower leg, upper arm, and rib. The tumour is composed of small round blue cells. Ewing’s sarcoma can also arise in soft tissue (extra-skeletal). http://www.cancerindex.org/ccw/guide2e.htm Patient and family information for Ewing’s Sarcoma: http://imsdd.meb.uni-bonn.de/cancer.gov/CDR0000403689.html Sources: http://www.cancerindex.org/ccw/guide2e.
This type of sarcoma is named after Dr James Ewing, who described the tumour in the 1920s. It is a cancer which can develop anywhere in the body, although it most often starts in the bone (a primary bone tumour). Any bone can be affected, but the pelvis, thigh bone (femur) and shin bone (tibia) are the most common places. Ewing’s sarcoma is most commonly found in teenagers and young adults, and is slightly more common in males than females. Although Ewing’s sarcoma is a type of bone cancer, Ewing’s sarcoma can also very rarely occur in the soft tissues rather than starting in bone. This is called an extraosseous Ewing’s sarcoma. Sometimes these cancers are called primitive neuroectodermal tumours (PNET). Sources: http://www.cancerbackup.org.
Ewing sarcoma is a malignant round-cell tumor. It is a rare disease in which cancer cells are found in the bone or in soft tissue. The most common areas in which it occurs are the pelvis, the femur, the humerus, and the ribs. Because a common genetic locus is responsible for a large percentage of Ewing sarcoma and primitive neuroectodermal tumors, these are sometimes grouped together in a category known as the Ewing family of tumors.[1] The diseases are, however, considered to be different: peripheral primitive neuroectodermal tumors are generally not associated with bones, while Ewing sarcomas are most commonly related to bone.
