Calcified epithelioma is one of the pilomatricomas and is most common in the head and neck area around the auricular region. It is often treated by dermatology and plastic surgery and is not well recognized in dentistry. In the present study, we experienced a case in which a calcified epithelioma was removed from a patient who underwent continuous dental treatment since immediately after the onset of systemic lupus erythematosus. The tumor lesion was indistinct in the panoramic radiographs at the time of initial examination, but five years later, a well-defined opaque border around the mandibular branch was clearly visible. CT images revealed a 10mm-sized mass lesion with calcification just under the skin in front of the earlobe, which was excised under general anesthesia. The histopathology showed a nodular lesion with calcification, consisting of shadow cells and acidophilic, unstructured material, which was a calcified epithelioma. Three months after surgery, no recurrence has been observed.
