Periosteal Chondrosarcoma of the Maxilla

Abstract

Primary chondrosarcomas of the head and neck region are exceedingly rare neoplasms. These lesions have clinical and histologic characteristics that make them difficult to discern from benign chondromas. Additionally, they may arise from the periosteum, making it even more difficult to distinguish them from osteosarcomas. We present a patient with a periosteal chondrosarcoma of the maxilla. Characteristic radiologic and histologic findings associated with this lesion are described. This is the first reported case of such a lesion in the maxilla, as previous reports of periosteal chondrosarcomas have involved long bones. The diagnostic dilemma posed by this extremely unusual lesion is discussed, as well as treatment options.
