Roentgenologic Considerations in the Diagnosis and Treatment of Primary Malignant Bone Tumors

Bone tumors have been classified by Dr. Willis C. Campbell (1) into two groups: first, osteogenic tumors, arising from elements needed in the formation of bone, namely the fibroblast, chondroblast, and osteoblast; second, non-osteogenic tumors, arising from tissues resident in bone, “but in no measure connected with the formation of bone.” More recently, Ewing (2) presented a revised classification in a report from the Committee of the Registry of Bone Sarcoma of the American College of Surgeons. The first three classifications in this new listing include tumors arising from elements needed in the formation of bone, namely osteosarcoma, osteo-chondroma, and giant-cell tumor, while the last four classifications consist of tumors apparently arising from elements resident in bone, namely angioma, myeloma, lym-phosarcoma, and liposarcoma. The full classification is as follows: 1.  Osteogenic Series: Osteogenic Sarcoma 1. Medullary and subperiosteal 2. Telangiectatic 3. Sclerosing 4. Periosteal 5. Fibrosarcoma...
