Juvenile ossifying fibroma of the mandible. An 8 year radiological follow-up.

An 8-year follow-up of a juvenile ossifying fibroma in the left mandible of a 4-year-old boy is presented. The case demonstrated initial lack of radiological evidence of demarcation and subsequent eccentric enlargement, selective tooth displacement and a multilocular appearance in areas of active growth. An aneurysmal bone cyst and a decrease in the bone content was present in the excision specimen.
