Description

Calcifying epithelioma is a type of tumor that arises from hair matrix cells and frequently occurs in the face and upper limbs of young people. It is usually treated by dermatologists and plastic surgeons. This case report is unusual as it describes calcifying epithelioma that was treated by otolaryngologists. Because calcifying epitheliomas rarely recur or undergo malignant transformation, we should take notice of them. Our first patient was a 15-year-old girl who presented with a chief complaint of a mass on the lower left ear. Findings of fine-needle aspiration cytology and computed tomography indicated calcifying epithelioma. Our second patient was a 13-year-old boy who presented with a chief complaint of a right submandibular mass. Computed tomography and magnetic resonance imaging indicated calcifying epithelioma. The masses in both patients were surgically excised under general anesthesia and the histopathological findings confirmed calcifying epithelioma. The postoperative courses of both have been good, without recurrence.
