Chondroblastoma is a rare type of non-cancerous tumor that develops in the cartilage at the end of long bones, especially near arm bones at the shoulder and near leg bones at the hip or knee. The tumors likely start in immature cells that produce cartilage, the flexible connective tissue that protects joints and bones.

Risk and symptoms

Chondroblastoma can affect people of any age, but it is most often seen in children and young adults. About 80% of cases are males under age 25. The most common symptoms are pain, joint stiffness, fluid in the joints, and muscle loss. Since the tumor is within the bone, there is not a lump or mass that can be felt.
