Solitary peripheral osteoma of the mandible: Report of 2 cases

Abstract

Osteomas are benign slow-growing lesions. A very few cases of the peripheral type arising from periosteum have been reported. In the facial region, periosteal osteomas mostly occur in the paranasal sinuses; thus, solitary osteomas of the jaws bones are rare. The etiology is unknown although it could be attributed to as a developmental anomaly, due to trauma or infection. Herein, we have reported two cases of large solitary peripheral osteoma discussing the clinical, radiological, and histological features of the lesion located in the buccal and lingual surface in the left posterior part of mandible causing facial asymmetry and the other being asymptomatic.
