A 6 year-old boy with a mandibular expansion.

Clinical informationThe patient was a 6 year-old boy. He was brought to his pediatrician because of a painless mandibular expansion on his left side. His pediatrician noted a smooth expansion in his left mandible and at the same time the first molar has not erupted over the expansion. The patient was referred to the clinic of a local dental school for treatment. On physical examination, the patient was afebrile. Development of his face and skull appear to be within normal limits except for the aforementioned expansion. There was no sign of dental infection or sinus drainage site. A panoramic view was taken and demonstrated a well defined multilocular lesion that involves the molar ramus of the left side of his mandible. The lesion was excised. The followings are representative images.
