Cemento-ossifying fibroma (COF) is a benign fibro-osseous lesion which belongs to the same category of fibrous dysplasia and cement-ossifying dysplasia. It arises from the periodontal membrane which contains multipotent cells that are capable of forming cementum, lamellar bone, and fibrous tissue. It is more common in the mandible than in the maxilla. We present a case of COF in the maxilla, a rare occurrence in a 66-year-old female with the chief complaint of a swelling in the left upper back tooth region for the past 3 years. A panoramic radiograph was taken, which showed an oval radiopaque lesion in the second quadrant from 24 to maxillary tuberosity. In the maxilla, the clinical and radiological differential diagnosis includes fibrous dysplasia, giant cell lesions, cementoblastoma, calcifying epithelial odontogenic tumor, and peripheral giant cell granuloma. It is sharply circumscribed and demarcated from the surrounding bone, so surgical excision is the treatment of choice.
