In respect to histological type of tumors, the following categories were defined: conventional osteosarcoma (covering osteogenic as well as chondroblastic and fibroblastic osteosarcoma), telangiectatic osteosarcoma, secondary osteosarcoma related to Paget's disease, intraosseous low-grade osteosarcoma, parosteal osteosarcoma, periosteal sarcoma, and high-grade surface osteosarcoma.
The precise cause of ionizing radiation-induced periosteal sarcoma is unknown although genetic factors have been suspected.
For example, intramedullary sarcomas are markedly more aggressive tumors as a group than are periosteal sarcomas.[3]
