We report a rare case of ossifying fibroma of the maxillary bone. This patient was a 48-year-old female with pain and swelling on the left root of the nose. CT scan demonstrated a broken appearance of the anterior wall of the maxillary sinus and a ground-glass appearance of the maxillary bone. We performed Caldwell-Luc procedure under general anesthesia to rule out malignant neoplasm. The pathological diagnosis was ossifying fibroma of the maxillary bone. Ossifying fibroma is a benign neoplasm, but classification of this tumor is under discussion. We describe the diagnosis and classification of this tumor with reference to the literature.
Key words : ossifying fibroma, maxillary bone, classification
