Only one correct answer.

1.) Ewing sarcoma is a malignant tumor of the cartilage.

2.) Primary treatment is a limb-salvage procedure.

3.) The cancer originated in the osteoblasts.

4.) Rare under the age of 30.

Answer 1

The cancer originated in the osteoblasts would be consistent with a diagnosis of ewing sarcoma,

Once it was thought that ewing sarcoma to be derived from neuroectodermal cells, but now it is believed that it arises from mesenchymal stem cells or osteoblasts. The morphology of osteoblast cells is changed to resemble ewing sarcoma.

Ewing sarcoma is cancer of bones & soft tissues that involve legs, pelvis & chest wall. It spreads mostly to lungs, other bones or bone marrow.

Limb-salvage is surgery in which the tumor from limb is removed & the surrounding tissues are also removed, & an implant is used to replace the part of limb removed. This procedure would be carried out if the pharmacological treatment fails.

Ewing sarcoma is a rare type of cancer that has usual onset from 10 - 20 years of age.
