Cemento-ossifying fibroma. As opposed to fibrous dysplasia, cemento-ossifying fibroma is a neoplasm. It has a distinct border/capsule, which is demarcated from the surrounding jaw bone radiographically and histologically. Unlike fibrous dysplasia, there is a wide range of osteoid, woven bone production, and poorly formed trabeculae. In addition, small spherules of eosinophilic material are commonly seen on hematoxylin and eosin stained sections. These small structures of cementum-like material show a peripheral eosinophilic ‘brush border’ at their periphery.
