Psammomatoid ossifying fibroma.
Psammomatoid ossifying fibroma (POF) represents a unique subtype of fibro-osseous lesions. We describe a case of POF involving the orbit and the sinonasal tract, in a 13-year-old white female. Diagnosis depends on the histological, radiological and clinical features. Complete excision by endoscopic nasal surgery was the treatment of choice. Five years later the patient was free from symptoms and tumour recurrence. Differential diagnoses are discussed.
