Osteogenic osteosarcoma of the orbit is a rare and aggressive type of osteosarcoma. Head and neck osteosarcomas occur most commonly in the third and fourth decades and have equal sex predisposition. A 56-year-old male patient was admitted to our clinic with proptosis on the left side and ptosis that had been present for five months. Ophthalmic examination revealed normal eye movements and vision. There was no pain and no paresthesia or any other significant complaint or clinical finding. Magnetic resonance imaging studies showed a hyperintense, destructive extraconal mass lesion adjacent to the lateral wall invading retrobulber fat tissue of the left orbit. The patient underwent a lateral orbitotomy. Histopathological examination revealed osteogenic osteosarcoma of the orbit.
