Chondrosarcoma of the maxilla extending to the pterygomandibular space: a case report and review of the literature.

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.
