Trichilemmal carcinoma is an uncommon cutaneous neoplasm that occurs in sun-exposed areas of older persons. It is thought to be related to the external root sheath of the hair follicle and to be the malignant counterpart of a trichilemmoma. We describe a case of trichilemmal carcinoma treated with Mohs micrographic surgery.
