We have described two cases of ossifying fibroma in this paper.
The first one was a recurrent case which occurred in a 52 year-old male patient. Tumor masses were found in the lower rim of mandible and in scar tissue close to previously operated areas. Histopthological examination revealed that tumor masses were composed of a proliferation of spherical and trabecular bones and dense fibrous tissue with a high cellularity.
The second one was a case observed in a 26 year-old female patient. Histopathological examination revealed that the majority of tumors consisted of a proliferated fibrous tissue and a few immature fibrous bony tissues that were scattered at the peripheral region of this fibrous tissue.
Although the enucleation of tumor or marginal resection of mandible were recommended for the treatment of ossifying fibroma, more extensive continuous resection of mandible should be applied to the cases which small tumor nests were scattered throughout the mandible such as case 1.
