Infiltrating floor of mouth lipoma plunging through the mylohyoid

Lipomas are commonly occurring benign adipocytic tumours of mesenchymal origin and can be found anywhere there is native fatty tissue. In the head and neck region, they typically arise in the cervical fibrofatty tissue of the neck and rarely originate intraorally. Intraoral lipomas can arise out of the sparse sublingual fat and be intimately involved with the tongue and floor of the mouth musculature. This case report highlights a rare infiltrating intraoral lipoma in the floor of the mouth region involving the mylohyoid.
