Periosteal Osteosarcoma of the Mandible

Abstract

This is a case report of a rare malignant mesenchymal tumor, juxtacortical (periosteal) osteosarcoma arising from the mandible in a 17 year old boy. About 4%-6% of osteosarcomas occur in the maxillofacial region, while incidence of osteosarcoma occurring in jaw is 0.7 per million population. Due to its unique feature, they are high number of chances of misdiagnosing the tumor with other peripheral fibro-osseous lesions. The prognosis of the tumor is good if detected early and a wide margin resection is performed to make the recurrence obsolete.
