Osteosarcoma: A rare case report and review of literature

Abstract

Osteosarcoma of the jaws is a rare, aggressive, malignant mesenchymal tumor with an estimated incidence of 5% in 100,000 of the new cases per year. Osteosarcoma of jaws is a very rare disease and may constitute approximately 1% of all head and neck cancers and only 0.14% of intraoral malignancies. Approximately 7% of all osteosarcomas arise in the jawbones. Diagnosis of the tumor is important, especially in early stages for improving prognosis. Here, we report a rare case of osteosarcoma of chondroblastic variant in a 20-year-old girl, who presented with a bony swelling in the right mandibular posterior region, with a radiographic presentation of sunburst appearance, and the histopathological examination confirmed the diagnosis.
