Osteochondroma of angle of the mandible: a case report

Osteochondroma / osteocartilagenous exostosis is a cartilage-capped exophytic lesion that arises from the cortex of bone.It constitutes 20 -50% of all benign tumours and 10 -15% of all bone tumours, but it is actually a developmental lesion rather than a true neoplasm.However, this process only rarely affects the craniofacial bones.In the craniofacial region, condyle and coronoid process of the mandible are the most commonly affected areas.This lesion may present in a solitary fashion or as multiple osteochondromas as part of an inherited syndrome that results in disturbances of skeletal growth and development.The treatment of osteochondroma is primarily surgical resection of the tumours.The present article reports the extremely rare case of OC arising from the angle of the mandible causing facial asymmetry.
