Juxtacortical or parosteal osteogenic sarcoma is a well-known entity to orthopedic surgeons, but it has not previously been encountered or described in the journals of otolaryngology. A perusal of the world literature fails to reveal the record of a single instance of parosteal sarcoma of the mandible. The U. S. Army Medical Museum has registered this case as the first to be recorded in the mandible.
Dr. H. L. Jaffe describes juxtacortical osteogenic sarcoma as a distinctive bone-forming connective-tissue tumor, which develops in relation to the surface of a bone and specifically in relation to the periosteum and/or the immediate parosteal connective tissue. As such it must be distinguished from conventional osteogenic sarcoma of bone which arises centrally from within the affected bone.1
L. Lichtenstein believes that juxtacortical sarcoma is related to foci of myositis ossificans or to atypical osteochondromas, but contains sarcomatous elements of lesser or greater malignancy.
