Juvenile ossifying fibroma is an expansive intraosseous lesion of the bones. In most patients, the tumors are located in the facial bones. The main characteristics of juvenile ossifying fibroma are the early age of onset, localization of the tumor, radiological pattern and a tendency for recurrence. This article describes a case of expanded juvenile ossifying fibroma in the right maxilla in a 12-year old boy. The lesion was removed totally by surgery under general anesthesia. The patient showed no radiological signals of recurrence approximately two years after surgery.
