What is chondroblastoma?

Chondroblastoma, also called a calcifying giant cell tumor or Codman tumor is a rare, non-cancerous tumor made up of a mass of cartilage tissue. The tumor forms when your cells grow and divide more than they should or don’t die when they should (neoplasm). Chondroblastoma forms on the joint end of long bones near the growth plate and is most often found on your thigh (femur), upper arm (humerus) and shin (tibia).
