title: [Periosteal osteosarcoma of the jaw. Apropos of 2 cases].
abstract: The authors report two cases of periosteal osteosarcoma of the jaws, a tumour which is one of the two variants of juxtacortical osteosarcoma. Periosteal osteosarcoma involving the jaw bones is extremely rare. Because of its chondroblastic differentiation, sometimes predominant, this tumour may pose some problems of differential diagnosis with chondrosarcoma or pleomorphic adenoma: immunochemistry may be necessary. This localization does not change the clinical, radiologic, histologic and prognostic features of periosteal osteosarcoma.
