Peripheral osteoma of the zygoma: literature review and case presentation.

Osteoma is a benign, bone forming tumor that is uncommon in the jaws. The aetiology of osteomas is unknown but trauma, infection and developmental abnormalities have been implicated. Solitary osteoma may be classified as peripheral, central and extraskeletal, while multiple osteomas may be associated with Gardner's syndrome. We report a case of solitary peripheral osteoma of the zygoma with a review of literature.
