Myxoid Liposarcoma of the Oral Cavity: Case Report and Review of the Literature

Liposarcomas very rarely affect the oral cavity; in such cases the cheek is typically involved. Differential diagnosis between lipoma and other sarcomas is sometimes challenging because the macroscopic and histological features may be difficult to distinguish. Neoplasms with the morphology of lipoma should always receive a careful postoperative histopathologic evaluation. Complete surgical excision is the most effective treatment. We present a case of myxoid liposarcoma of the cheek, together with a literature review of intraoral liposarcomas reported during the last 60 years.
