Abstract Lipomas are benign soft-tissue mesenchymal tumors commonly occurring in the region of the neck, and less frequently on the back, arm, shoulder, anterior chest wall, breast, thigh, abdominal wall, leg, forehead, and face, in that order. 1 Several cases of oral lipomas have been reported. They are generally found in the tongue, buccal mucosa, gingiva, and labial and buccal folds. 2,3 Infiltrating lipoma, also referred to as an intramuscular lipoma, is an unusual form of this benign neoplasm, originating between skeletal muscle bundles and infiltrating through the intramuscular septa. 4–7 These lipomas are generally found on the upper or lower limbs, and are exceedingly rare in the oral cavity. Only six cases have been reported. 5,8–11 Because of the rarity of these tumors and their high rate of recurrence without adequate surgery.
