Abstract

Radiographic examinations complement the anamnesis and physical exam with the purpose of reaching diagnosis, prognosis and treatment planning. In this case report, a 48 year-old male Caucasian patient was referred to an oral and maxillofacial surgeon by a general practitioner after a panoramic radiography for treatment planning; the implant surgery follow-up portrayed a multilocular radiolucent image at the left posterior mandible. Based solely on the panoramic radiography, the diagnostic hypothesis was ameloblastoma. The surgeon decided to perform an incisional biopsy. However, during the procedure, the professional noted that the lesion was easily detached from the adjacent bone and opted for the total removal of the lesion, thus altering its diagnostic hypothesis to central ossifying fibroma (COF). The histopathological result confirmed the diagnostic hypothesis provided by the surgeon, i.e. COF. Although multilocular presentation is not common, COF should be considered in the scope of multilocular radiolucent lesions of the jaws. In addition, computerized tomography imaging exam complemented by surgical and histopathological aspects should be considered for establishing the final diagnosis and conducting the therapeutic approach.
