    Abstract:
    Juvenile ossifying fibroma is an uncommon, benign, bone-forming neoplasm with aggressive local growth that is distinguished from other fibro-osseous lesions primarily by its age of onset, clinical presentation and aggressive behavior. Although a benign entity, juvenile ossifying fibroma is known to be locally aggressive and has a high tendency to recur. Two distinctive microscopic patterns have been described: A trabecular variant and a psammomatoid variant. This latter variant is predominantly a craniofacial lesion and occurs rarely in the jaws. We present herein two cases of psammomatoid juvenile ossifying fibroma involving the jaws. The first case was a mandibular lesion in a 31-year-old female whereas the second case presented with maxillary involvement in a 46-year-old female. In addition, the pathology of the lesion was analyzed with confocal laser scanning microscopy.
