title: Ossifying fibroma of the occipital bone.
abstract: A rare ossifying fibroma in the occipital bone is described, and the available literature reviewed. The rapid growth seen in this case was remarkable and led us to believe this was a malignant osteogenic tumor. Full knowledge and the correct diagnosis of ossifying fibroma should have prevented an unnecessarily extensive operation for this benign lesion.
