Osteosarcoma

Osteosarcoma is a malignant bone cancer; together with Ewing's sarcoma it accounts for most primary bone malignancies. There is a preference for the metaphyseal region of tubular long bones. 50% of cases occur around the knee. It is a malignant connective (soft) tissue tumor whose neoplastic cells present osteoblastic differentiation and form tumoral bone.
