We report a case of sialolithiasis of the upper lip in an elderly person. A 78-year-old male was referred to our hospital because of a painless mass at the upper lip. Upon palpation, a painless mass at the left-side upper lip with the size of a grain of rice, elastic hardness, and mobility from the surrounding tissue was found. We diagnosed the lesion as a benign tumor of the upper lip, and excised it under local anesthesia. In the tumor, there was a hard calcification-like substance of about 2.5 mm in size and yellowish white in color. In the pathological examination and X-ray microanalysis, the material was diagnosed as caused by sialolithiasis of the upper lip over a long time, under the stable situation of little foreign stimulation.
