Abstract

Ossifying fibromas are benign fibro-osseous tumors of mesenchymal origin. Although ossifying fibromas have principally been found in the jaw, they have also been reported in the frontal, ethmoid, sphenoid, and temporal bones, as well as the orbit and anterior cranial fossa. Ossifying fibromas affecting the jaw exhibit variable behaviors ranging from slow growth to occasionally aggressive local destruction. In the present article, we discuss a differential diagnosis considered for maxillary swellings and report a rare case of ossifying fibroma occurring in the maxilla.
