Chondroblastomas are a rare type of noncancerous (benign) bone tumor that begins in is made up of cartilage cells. Chondroblastomas grow at the ends of the body’s long bones (called the epiphysis) near the joints.

Aneurysmal Bone Cysts are benign aggressive tumors that destroy bone. They most commonly affect the spine and growth plates of the femur and tibia.

Undifferentiated Pleomorphic Sarcoma (UPS) is the second most common bone sarcoma in adults after chondrosarcoma. Previously known as Malignant Fibrous Histiocytoma (MFH), UPS gets its name because of the way it looks under a microscope (histology). Undifferentiated describes how the cells do not look like the body tissues in which they develop. Pleomorphic means the cells grow in different shapes and sizes.

Telangiectatic Osteosarcoma is a cancerous bone tumor that produces bone. This type of tumor occurs primarily in the bone of the femur, and humerus.

A Periosteal Osteosarcoma is a cancerous bone tumor. It comes from within the bone (intramedullary). It is a cancerous tumor, and can lead to bone destruction. It is a slow growing tumor that will not spread to other parts of the body in most cases.

A low-grade sarcoma (cancerous; malignant) lesion that occurs on the surface of long bones and arises from the outer layer of the periosteum.The periosteum is the coating on the surface of the bone.

Conventional Osteosarcoma is the most common cancerous bone tumor that produces bone. This type of tumor occurs primarily in the bone of the femur, and humerus.

The most common type of primary bone cancer. This condition is a type of bone marrow cancer arising from plasma cells that can cause tumors in the bone. Plasma cells are normal cells in the blood that make antibodies.

Also known as Multiple Myeloma when it affects multiple bones. It is called a plasmacytoma when it affects a single bone.

Hemangiopericytoma of the bone is a malignant tumor originating from the cells around tiny blood vessels called capillaries (called pericytes). It most commonly affects the pelvis, femur, spine, and humerus.

This condition is a rare cancerous tumor composed of cells that make up the blood vessels, called endothelial cells. It is primarily seen in the lungs.
