Bony tumour in an unusual location on the mandible

ABSTRACT

Osteomas are benign osteogenic tumors that are seen in the facial bones, but uncommonly in the mandible. In the facial bones, both central and peripheral osteomas have been described. Peripheral osteomas have been described to occur in the frontal, ethmoid, and maxillary sinuses but are not common in jawbones. When in the mandible, they are usually found over the angle and inferior border of the mandible. We report on a solitary peripheral osteoma located unusually in the sigmoid notch of the left mandible causing facial asymmetry.
