In this paper, two cases of calcifying epithelioma arising in the mandibular angle are presented. Case 1 is a 10-year-old boy who had a painless tumor in the right mandibular angle region. Orthopantomograms revealed a radiopaque area in the region. Case 2 is a 49-year-old woman who had a painless tumor in the same region. In some X-ray photographs, there was no radiopaque area in the region. In both cases, examination of excisional biopsy specimens showed shadow cells in the tumor. In spite of the name “calcifying epithelioma, ” calcification is not present in some cases. In case 2, calcification was evident histopathologically, but not by X-ray examination. A radiopaque appearance is apparently not essential for the diagnosis of calcifying epitheliomas.
