Abstract
Ossifying fibroma (OF) is a fibro-osseous tumor that usually occurs in young people and arises in the craniofacial bones. We report a case of a 15-year-old boy who developed progressive proptosis and hypertelorism and was found to have a mid-face and skull base tumor, initially diagnosed as psammomatoid meningioma. The tumor recurred and the resected specimen revealed a unique OF having trabecular and psammomatoid features. The clinical, radiographic, histopathologic findings and differential diagnoses of the case are presented.
