Masses left behind by healed tissue after a fracture or by certain diseases such as bone tumors are called skeletal masses. The skeletal system, like other organs, can develop tumors from any tissue component or metastatic lesions from other organs. Tumors that invade the bone can occur in the bone cells, the hematopoietic component of the bone, the cartilage, and the fibrous or synovial component. Other tumors may arise from the muscles and nerves, blood vessels, and fatty tissue of the bone. Bone masses may not be felt at first, but may become swollen and painful when the mass is larger.
