    "definition": "A low grade osteosarcoma arising from the medullary portion of the bone. It affects the long bones and is characterized by the presence of fibroblastic stroma and osteoid production. Pain and swelling are the usual sign and symptom. The prognosis is more favorable than conventional osteosarcoma."

        "definition": "A usually aggressive malignant bone-forming mesenchymal neoplasm, predominantly affecting adolescents and young adults. It usually involves bones and less frequently extraosseous sites. It often involves the long bones (particularly distal femur, proximal tibia, and proximal humerus). Pain with or without a palpable mass is the most frequent clinical symptom. It may spread to other anatomic sites, particularly the lungs."
