Abstract: Chondroblastoma is a rare osseous tumor, whose incidence is less than 1% in all primary bone tumors. It is also a benign cartilaginous tumor, which affects the epiphyseal regions of the tubular bones. The tumor occurring in the head and neck region is uncommon. This paper reported one case about the primary condylar chondroblastoma and reviewed the relevant literature to discuss the radiographic features.
