Liposarcoma of the head and neck is rare. Because of its rarity, we report this case of pleomorphic liposarcoma of the left pterygomandibular space, involving the maxilla, maxillary sinus, left lateral maxillary wall, left maxillary gingiva with extension into the buccal space, retro-orbital region, left mandibular ramus, and left zygomatic process. To our knowledge, there are only two other reported cases of liposarcoma involving the maxilla, one of which was a pleomorphic liposarcoma. The pertinent literature is reviewed with an emphasis on the importance of histopathologic classification.
头颈部脂肪肉瘤较为罕见。鉴于其罕见性，我们报告这例左翼下颌间隙多形性脂肪肉瘤病例，该肿瘤累及上颌骨、上颌窦、左侧上颌窦壁、左侧上颌牙龈，并延伸至颊间隙、眶后区域、左侧下颌支及左侧颧骨突。据我们所知，仅有另外两例脂肪肉瘤累及上颌骨的报道，其中一例为多形性脂肪肉瘤。现对相关文献进行综述，并着重强调组织病理学分类的重要性。
