The age of the patient, radiographic appearance, and site of the tumor may help in some cases to distinguish between the different categories of lesions. Ewing’s sarcoma, for example, is a tumor more common in children and

Therefore the specific quality of bone matrix as a mineralizing connective tissue is probably due to its 10% noncollagenous protein content. Based on this assumption
