Osteogenic Sarcoma of Mandible.

Osteosarcoma (OS) is a malignant neoplasm characterised by the formation of osteoid matrix by neoplastic cells. It is the most common primary malignant bone tumor accounting for 20% of all sarcomas, although its occurrence in the jaw is rare. It shows typical clinical behaviour but varied radiological and histopathological features. It presents various histological aspects. We report a case of 30-year male presented with a painful swelling of mandible, diagnosed as OS after histopathological evaluation.
