Abstract
Calcifying epithelioma was reported by Malherbe et al. in 1880 as a benign tumor derived from hair matrix cells. Lesions appear most commonly on the face and neck and are palpated as firm subcutaneous nodules. A female in her 40s had had a mass in her left buccal region since her teenage years which she left untreated because it was asymptomatic. During a dental check-up, she was recommended to visit a clinic for the examination and treatment of her mass. Radiographic examination revealed the presence of calcification in the posterior region of her left mandibular angle. Enucleation was performed under local anesthesia based on a clinical diagnosis of ectopic calcification in the left masseter muscle and parotid gland region. A majority of the epithelial cells were shadow cells. Calcification and bone formation were observed around the shadow cells. The histopathological diagnosis was calcifying epithelioma. As for the postoperative course, no recurrence has been reported after 1 year and 6 months.
