Bone tumors in children. Differential characteristics and treatment.

Recognition of benign bone tumors in children is important so that they can be distinguished from malignant tumors, which pose a far more significant risk. Treatment is relatively uncomplicated for benign lesions, but malignant tumors present a significant challenge to the orthopedist, medical oncologist, and radiotherapist. Currently, strides are being made toward improving the survival rate and quality of life of bone sarcoma patients. Newer diagnostic techniques, such as magnetic resonance imaging, and improved research techniques, such as flow cytometry, may lead to further understanding of the nature of these virulent tumors. Improvement in biomechanical designs for metallic joint implants and further understanding of bone transplantation biology should result in better functional restoration in these patients.
