Chondrosarcomas are rare tumors of which approximately 10 % are found in the maxillofacial region. They range from a well-differentiated growth resembling a benign cartilage tumor to a high-grade malignancy with aggressive local behaviour and the potential to metastasize. We report a case of high-grade chondrosarcoma of the maxilla extending to the pterygomandibular space which was treated with radical surgical excision without neck dissection and postoperative radiotherapy. The diagnosis was a conventional type of chondrosarcoma, Grade III. The postoperative course was uneventful, and the patient has had no recurrence in the 15-year follow-up period.
软骨肉瘤是一种罕见的肿瘤，其中约10%发生于颌面区域。其生长范围从类似良性软骨肿瘤的高分化型到具有侵袭性局部行为及转移潜能的高级别恶性肿瘤。我们报告一例上颌骨高级别软骨肉瘤延伸至翼下颌间隙的病例，该病例接受了根治性手术切除，未行颈部清扫及术后放疗。诊断为传统型软骨肉瘤，Ⅲ级。术后过程顺利，患者在15年的随访期内未复发。
