Juvenile psammomatoid ossifying fibroma with secondary aneurysmal bone cyst of mandible

Juvenile psammomatoid ossifying fibroma (JPOF) is a rare, slowly progressive tumor of the extragnathic craniofacial bones, with a tendency towards locally aggressive behavior and recurrence. The pathognomonic histopathologic feature is the presence of spherical ossicles, which are similar to psammoma bodies. Very few cases in association with the secondary aneurysmal bone cyst (ABC) formation have been reported in the literature. Treatment consists of complete surgical removal; the incomplete excision has been associated with a high local recurrence rate. The prognosis is good because malignant change and metastasis have not been reported. We report a case of JPOF of the mandible with secondary ABC in an 18-year-old male patient.
