Intraoral Lipoma: A Rare Placement in Mental Foramen Area

Lipomas are the most common benign soft tissue tumors. They are usually surrounded by a thin fibrous capsule and composed of mature fat cells. Approximately 15 to 20% of cases occur in the head and neck region and only 1 to 4% occur in the oral cavity . The most common anatomic site in the oral cavity has frequently been reported as the buccal mucosa, followed by floor of the mouth, tongue and lower lip mucosa. They present as painless, well circumscribed, soft or firm, slow growing submucosal mass. Heredity, fatty tissue degeneration, hormonal imbalance, trauma, infection and chronic irritation have been proposed as etiological agents for lipomas; their etiology remains unknown.
