Abstract:

Juvenile Ossifying Fibroma (JOF) is a rare fibro-osseous neoplasm of the craniofacial bones, having locally aggressive behaviour and recurrence. The psammomatoid juvenile ossifying fibroma (PsJOF) is a variant of JOFs, occurring as extragnathic lesions in the sino-nasal and orbital bones. PsJOF is rarely seen in the jaw bones, with slight male predominance and mean age of occurrence between 16-33 years. PsJOF are central lesions manifesting radio-graphically as a radiolucent, mixed or radiopaque lesion which depends on the degree of calcification giving a ground glass appearance. PsJOF is histologically characterised by the presence of psammoma bodies which are concentric, lamellated calcified structures. We hereby report two unique cases of PsJOF, one occurring as a combined lesion, in association with Aneurysmal Bone Cyst in the maxilla and another case PsJOF presenting as soft tissue growth in an elderly female patient.
