[Calcifying epithelioma observed in the anterior auricular region]

Three cases of calcifying epithelioma observed in the anterior auricular region are reported. The ages were 9 to 15 years, and all were females. The size of the tumors ranged from 20 x 20 mm to 22 x 34 mm. One case showed elevated (4.1 ng/ml) SCC antigen preoperatively, however, the value was reduced within the normal range (1.3 ng/ml) after removal of the tumor. One case showed a fistula with brownish and serous discharge on the epithelial surface of the tumor. In the same case, mitotic change of basophilic cells in the tumor was observed, however, distinctly malignant changes such as cell invasion into the surrounding tissue were not observed. Although the head and neck region are the most common areas where calcifying epithelioma occur otolaryngologists do not have sufficient understanding of this disease. Therefore, epidemiology, clinical findings, clinical examination, pathology, therapy and prognosis of calcifying epithelioma were discussed.
