Trichilemmal carcinoma is a rare adnexal tumor originating from outer root sheath of hair follicle. We report a case of trichilemmal carcinoma occurring on the scalp. A 71-year-old women presented with a nodule on the vertex of scalp. Histopathologically, tumor cells showed a lobular proliferation in continuity with the epidermis. The lobules showed peripheral palisading and trichilemmal keratinization. The prominent tumor cells were large cells with PAS-reactive, diastase-sensitive, clear cytoplasm. Striking cytologic atypia and high mitotic index were found. Total excision was done and the patient has been free of recurrence or metastasis for 1 year.
