A 60-year-old woman consulted our clinic due to the presence of a mass in the right auricle for several years. On physical examination, a soft, dome-shaped, nodular non-tender mass was observed in the antitragus of the right auricle. The mass showed a central pit and multiple velli. On neck computed tomography, a slightly enhanced soft tissue density mass measuring 2 × 1.5 cm was observed in the right auricle. Based on an initial diagnosis of benign tumor, surgical excision was planned. In surgery under local anesthesia, the mass showed no invasion into adjacent tissues and was excised completely. Histopathological analysis indicated trichofolliculoma. Trichofolliculoma is a rare benign adnexal hamartomatous follicular tumor arising from the hair follicles. Trichofolliculoma is characterized by dome-shaped, skin-colored nodular or papular lesions with a central pore through which an immature hair protrudes. Trichofolliculoma is rare in the auricle and external auditory canal. Trichofolliculoma is usually asymptomatic, so treatment is usually not necessary. However, trichofolliculoma may cause disfigurement and the treatment of choice is surgical excision.
