[Osteochondroma of the mandibular condyle. Apropos of a case]

The authors report a case of mandibular condyle osteochondroma on a 33 years-old woman, similar to osteocartilaginous exostosis of the long bones. The lesion was revealed by a facial asymmetry and a change of the occlusion. The diagnosis was performed on the computed-tomography examination and histopathology. The removal of the lesion has conserved the condyle without recurrence after 20 months following-up. The authors remind the uncommonly location of osteochondroma in the facial skeleton and discuss the histogenesis of this lesion in its mandibular condyle site.
