Oral examination revealed no presence of the lower left first, second and third molars, and the tissue color of the region was light purple with an elastic hard consistency. The panorama roentgenogram revealed impacted molars, and an area of round multilocular radiolucency of about 30 mm. in diameter which surrounded the crowns of the impacted molars. It had the appearance of a follicular dental cyst. Under general anesthesia the lower left second and third molars were extracted, and the intra bony neoplastic tissue was enucleated, but with difficulty. The cut surfaces of removed tumors found to be solid. The pathologist report was neurofibroma similar to the cutaneous tumors. Healing was uneventful, and to date during the past three and a half years, postoperatively prognosis was good.
