Slowly enlarging pedunculated mass on the edentulous maxillary alveolar ridge

Peripheral ossifying fibroma is a fairly common, benign, reactive lesion that should be included in the differential diagnosis of slow-growing, nonaggressive tumors arising in the tooth-bearing areas of the jaws. The variations in terms and descriptions may require that the clinician communicate with the pathologist to determine the true nature of the lesion. Although peripheral ossifying fibroma is a benign, reactive lesion, the recurrence rate is fairly high and postoperative follow-up is needed.
