Peripheral osteoma of the mandible: case report and review of the literature.
BACKGROUND
Osteoma is a benign often asymptomatic neoplasm, consisting of well-differentiated mature bone. This paper reports a case of peripheral osteoma located in the anterior mandibular region and provides a review of the literature about this lesion in the jaws.


METHODS
A 43-year-old white woman presented with a swelling in the left mandible of 7 years duration. The English literature was reviewed over the past 76 years and data about location, histopathology and number of the peripheral osteomas, sex, and age of the patients were evaluated.


RESULTS
Data analysis showed 69 well-documented cases of peripheral osteoma. Peripheral osteomas are more frequent in the mandible than the maxilla and the cancellous type was most frequent; males and females are equally affected in the mandible; the age range was 9-85 years.


CONCLUSIONS
The peripheral type of osteoma is most common in the lower jaws, occurs at the surface of the cortical bone and is sessile or pedicled.
