Osteosarcoma of the jaw. A brief review and a case report.

Osteosarcoma of the jaws accounts for 6-13% of all osteosarcomata. If not diagnosed early, it spreads extensively through the jaw and contiguous soft tissues into the nasal cavity, the maxillary sinus, the orbit and the infratemporal fossa, and may invade the oral soft tissues. A clinical finding of tooth displacement and tooth mobility associated with radiolucency/radiopacity should alert the practitioner to the possibility of osteosarcoma or some other malignancy.
