A Case of Juvenile Psammomatoid Ossifying Fibroma on Skull Base

Juvenile psammomatoid ossifying fibroma (JPOF) is a fibroosseous tumor that arises in the craniofacial bones in young people. This lesion usually originates in the jaw, orbit, and ethmoid complex but can also be associated with the skull base and calvaria. Diagnosis must be made based on observing typical radiological and histopathological features. Although JPOF is a rare pathological entity, neurosurgeons must consider this odontogenic lesion in the differential diagnosis of skull masses given the lesion’s aggressive behavior and locally invasive growth. Treatment must be gross-total resection. In the following article, the authors present a case of cranial JPOF and discuss various aspects of this entity.

Active Processes

Juvenile psammomatoid ossifying fibroma (JPOF) is a benign fibro-osseous lesion typically associated with the jaw, paranasal region, or orbit. However, JPOF may also originate from the skull base and locally invade the cranium. In published reports, intracranial JPOFs constitute only a small percentage of cases, and therefore it is not known whether more aggressive behavior typifies this distinct population of JPOFs compared with those in other locations. Nevertheless, JPOF histopathology is characterized by a number of active processes, including cystic transformation, that may precipitate violation of skull base boundaries. In the following article, the authors present a case of skull base JPOF that underwent cystic expansion in a young girl, produced a focal neurological deficit, and was resolved using a staged surgical approach.

Psammomatoid Ossifying Fibroma

Juvenile Psammomatoid Ossifying Fibromais a rare fibro-osseous tumor seen in children and adolescentand mostly arising from the cranio-facial bone.We report a case of 18-year-old boy who presented with diplopiaand progressive right fronto-orbital swelling. On plain radiograph and CT, it was diagnosed as fibrous dysplasiaand mucocele as differential diagnosis. The tumor was resected and histopathological examination showed psammomatoid features. Therefore, the diagnosis of Juvenile Psammomatoid Ossifying Fibroma must be based on both radiological and histopathological findings.
