[Current treatment methods for osteosarcoma of the jaw bones].

It is also the most common primary malignant lesion of bone, excluding multiple myeloma. However it is rare: it occurs in 1 per 100,000 persons per year, and about 6% tot 7% of all osteosarcomas occur in the maxillofacial region. In this report, we discuss two cases of osteosarcoma in the maxillofacial region: one in the mandible and one in the maxilla. It is also a review of the literature. We discuss in detail the natural history of osteosarcoma in the jaw bones, the predisposing factors, the localisation, the presenting symptoms, the radiology and the methods of treatment.
