Tricilemmoma is a benign, solitary tumor that may be clinically misdiagnosed as basal cell carcinoma or verruca. It affects frequently the face of elderly rnen. We present herein a case of trichilemrnoma in a 70-year-old Korean wornan who had a slowly growing tumor on the scalp for 50 years. The histopathologic findings revealed lobular acanthosis of glycogeri rich clear cells and palisade of columnar cells resting on prominent basement membrane.
