Abstract

Intraoral lipomas are a rare clinical entity, comprising only 0.1% to 5% of all benign tumors in the intraoral cavity. A 56-year-old woman suffering from diabetes presented with this relatively rare intraoral lipoma and was treated by surgical excision under general anesthesia. Because the mass was located adjacent to the mental foramen, a precise dissection was necessary to ensure minimal nerve damage. No abnormalities or recurrence was noted at 1-year follow-up and the patient did not complain of numbness. We studied the occurrence of oral lipoma in this diabetic patient and reviewed the relationship between oral lipoma and diabetes in the literature.
