  • Chondroblastoma
    A chondroblastoma is a rare type of noncancerous bone tumor that begins in cartilage. This is the specialized, gristly connective tissue from which most bones develop. It plays an important role in the growth process. There are many different types of cartilage in the body. Chondroblastoma most often affects the ends of the long bones, near the growth plate, in the arms at the shoulder, and in the legs at the hip and knee. It is also called Codman’s tumor.
  • Enchondroma

    An enchondroma is a type of noncancerous bone tumor that begins in cartilage. An enchondroma most often affects the cartilage that lines the inside of the bones. It often affects the tiny long bones of the hands and feet. It may also affect other bones such as the femur (thighbone), humerus (upper arm bone), or tibia (one of the two lower leg bones).

  • Giant Cell Tumor

    A giant cell tumor is one that is made up of a large number of benign (noncancerous) cells that form an aggressive tumor. It usually develops near a joint at the end of the bone. The location of a giant cell tumor is often in the knee, but can also involve the bones of the arms and the legs, or the flat bones such as the breastbone or pelvis.

  • Osteochondroma
    Osteochondroma is an overgrowth of cartilage and bone at the end of the bone near the growth plate. Most often, it affects the long bones in the leg, the pelvis, or the shoulder blade.
