Periosteal osteogenic sarcoma of the mandible.
Periosteal osteosarcoma, a variant of juxtacortical osteosarcoma, is seldom seen in the jaws. The clinical, radiographic, and histopathologic features of a rare mandibular periosteal osteosarcoma presenting as a deep mass in the area of the parotid are reported. The clinicopathologic features that distinguish this lesion from the more common parosteal osteosarcoma are also discussed.
