Giant dedifferentiated liposarcoma of the right hemifacial area involving the oral cavity

Although liposarcoma is a reasonably common soft tissue sarcoma in adults, its occurrence within the head and neck region is very rare. The following report presents the case of a giant dedifferentiated liposarcoma initially located in the temporal region and then extending to the entire right maxillofacial region. Clinical as well as histopathological features and therapeutic approaches of dedifferentiated liposarcoma are discussed, and a literature review is presented. © 2011 The Gerodontology Society and John Wiley & Sons A/S.
