The occurrence of this malignant osseous tumor in the head and neck region, especially the mandible, is rare. In 1986 Weiss and Bennett 2 reviewed the literature of chondrosarcoma involving the head and neck region and documented 161 cases, of which 56 involved the mandible. Even more rare is the occurrence of chondrosarcoma arising from the temporomandibular joint (TMJ). A current review of American and European literature revealed only 6 cases originating at the TMJ, the most recent of which was reported by Nitzan et al 3 in 1993. In this article an additional case of chondrosarcoma of the TMJ is presented. Pertinent clinical aspects, including presenting features, radiographic findings, histopathology, and treatment of chondrosarcoma of the mandible are discussed. Chondrosarcoma arising in the TMJ is emphasized because tumors at this site present a special management challenge because of the involvement of the cranial base and the temporal bone.
