Current trends in the diagnosis and treatment of malignant bone tumors. 1983

F Schajowicz

After a review of the potential of current methods of investigation and of the slightly modified WHO bone tumor classification, the following neoplastic lesions, the diagnosis and treatment of which still present some unsolved problems, are described in detail: giant cell tumor (osteoclastoma); osteosarcoma, with special reference to malignant osteoblastoma; periosteal osteosarcoma and its disputed relation with or supposed identity to juxtacortical chondrosarcoma; Ewing's sarcoma; and malignant fibrous histiocytoma.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D009626	Terminology as Topic	Works about the terms, expressions, designations, or symbols used in a particular science, discipline, or specialized subject area.	Etymology,Nomenclature as Topic,Etymologies
D010017	Osteoma, Osteoid	A benign osteoblastic tumor with central vascularized nidus surrounded by normal reactive bone. It occurs especially in second decade of life most commonly in the femoral neck but can occur in any bone and any site within a bone.	Osteoid Osteoma,Osteoid Osteomas,Osteomas, Osteoid
D010521	Periosteum	Thin outer membrane that surrounds a bone. It contains CONNECTIVE TISSUE, CAPILLARIES, nerves, and a number of cell types.
D001842	Bone and Bones	A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principal cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.

D002813	Chondrosarcoma	A slowly growing malignant neoplasm derived from cartilage cells, occurring most frequently in pelvic bones or near the ends of long bones, in middle-aged and old people. Most chondrosarcomas arise de novo, but some may develop in a preexisting benign cartilaginous lesion or in patients with ENCHONDROMATOSIS. (Stedman, 25th ed)	Chondrosarcomas
D005870	Giant Cell Tumors	Tumors of bone tissue or synovial or other soft tissue characterized by the presence of giant cells. The most common are giant cell tumor of tendon sheath and GIANT CELL TUMOR OF BONE.	Cell Tumor, Giant,Cell Tumors, Giant,Giant Cell Tumor,Tumor, Giant Cell,Tumors, Giant Cell
D006651	Histocytochemistry	Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods.	Cytochemistry
