Juvenile psammomatoid ossifying fibroma: a rare cause of unilateral proptosis.

This is case of a young girl who presented with unilateral proptosis. Imaging (CT & MRI) revealed an expansile lytic bony tumour involving the left frontal bone and orbital roof. The globe was displaced but uninvolved. Complete surgical resection was done and histopathology revealed psammomatoid bodies diagnostic of juvenile psammomatoid ossifying fibroma (JPOF). JPOF is a rare bone tumour characterised by a predilection for the sino-nasal tract and orbit, a tendency to affect younger patients, a potential for aggressive growth and a high recurrence rate of 30-50%. It warrants a complete surgical resection to avoid recurrence.
