Abstract

Chondrosarcoma is a rare malignant neoplasm which constitutes approximately 10% of all primary malignant bone tumors. It occurs most often in the pelvis, femur, rib and humerus and the involvement of the jaw is rare, and what is more, chondrosarcoma arising in the condyle is extremely rare and only a few cases were previously reported and there is no domestic report. We report a chondrosarcoma of a condyle presenting as a painful swelling on the left preauricular area.
