A rare type of benign bone tumor that originates from cartilage, the specialized, gristly connective tissue from which most bones develop.


A malignant type of bone cancer that primarily affects the cartilage cells of the femur (thighbone), arm, pelvis, knee, and spine. Although less frequent, other areas (such as the ribs) may be affected.


A type of benign bone tumor that most often affects the cartilage that lines the inside of the bones of the hands and feet typically.

Ewing's sarcoma

A type of cancer that occurs primarily in the bone or soft tissue, most often found in the extremities and can involve muscle and the soft tissues around the tumor site as well as spread to other areas of the body.

Fibrous dysplasia

A chronic disorder in which bone expands due to abnormal development of fibrous tissue, often resulting in uneven bone growth, pain, and brittle or deformed bones.

Giant cell tumor

A type of tumor made up of a large number of benign cells that form an aggressive tumor, usually near the end of the bone near a joint.

Multiple myeloma

A type of cancer that affects certain white blood cells and collects in the bone marrow and the outer layer of the bone.


An overgrowth of cartilage and bone near the end of the bone near the growth plate, most commonly affecting the long bones in the leg, the pelvis, or shoulder blade.

Osteogenesis imperfecta

Also known as brittle-bone disease, a genetic (inherited) disorder characterized by bones that break easily without a specific cause.


An inflammation or swelling of bone tissue that is usually the result of an infection.


A type of bone cancer, most often occuring in children, adolescents, and young adults, that develops in the osteoblast cells that form the outer covering of bone.

Paget's disease

A chronic disorder that can result in enlarged and misshapen bones, accompanied by pain, fractures, and arthritis in the joints near the affected bones.

Hyperparathyroidism (primary hyperparathyroidism)

A metabolic disorder in which one (or more) of the parathyroid glands produces too much parathyroid hormone, which can result in the loss of bone tissue.
