Peripheral osteomas are rare tumors of jaws arising from proliferation of cancellous or compact bone increasing in size by continuous bone formation. These lesions appears as unilateral, pedunculated or sessile mushroom like masses, well marginated and varying in diameter from 10 to 40 mm. Osteomas are essentially restricted to craniofacial skeleton and are rarely if ever diagnosed in other bones. Osteomas are found mainly in craniofacial bones. They occur most frequently in paranasal sinuses followed by external ear canal, orbital wall, temporal bone and pterygoid processes and rarely in mandible. Mandibular osteomas originate mainly from lingual aspect of body of mandible and lower border in region of angle being the most common site. A rare case of peripheral osteoma of mandible arising from lower border in angle region has been presented here.
