Well-differentiated liposarcoma of the floor of the mouth: Report of a rare case and review of the literature.

Liposarcomas are extremely rare in the oral cavity. Less than 100 cases of oral liposarcoma have been reported in the world wide literature, mostly occurring in the buccal mucosa, whereas only <10 cases have been reported in the floor of the mouth. We present a rare case of oral liposarcoma that occurred in the floor of the mouth of a 45-year-old female patient.
