A large psammomatoid ossifying fibroma with proptosis: A case report.

The psammomatoid ossifying fibroma (POF) is a rare and benign fibro-osseous lesion predominantly affecting the paranasal sinuses and orbits of children and young adults. The diagnosis and management of the lesion remains challenging. The present study reported a rare case of a large POF in a 39-year-old male patient. The patient had a 30 year history of a slowly growing tumor and this had resulted in right craniofacial deformity, as well as right lateral displacement of the eye ball. Due to the large tumor size, surgical removal of the lesion was the predominant treatment. At 5 months after complete surgical resection, the patient was free from any symptoms. The radiological and histological findings, as well as the surgical management, were presented and the relevant literature was reviewed.
