Which term describes a malignant bone tumor arising from connective tissue?

• A. Osteoarthritis (OA)
• B. Scoliosis
• C. Osteosarcoma
• D. Osteochondritis

Answer: (C)

A malignant bone tumor that arises from connective tissue is osteosarcoma, which comes from osteogenic cells that produce bone (osteoid). This makes it the classic example of a malignant neoplasm of the bone’s connective tissue. It’s typically aggressive and often affects the metaphysis of long bones, like the femur or tibia, especially in adolescents. The other terms describe non-tumor bone or joint conditions: osteoarthritis is a degenerative joint disease, scoliosis is a spinal curvature, and osteochondritis is inflammation of bone and cartilage.
