A 74-year-old man asks about a lesion on the back of his right ear (Figure 169-1). It has been present for approximately 5 years. Although the lesion does not bother him, his wife is concerned because it has been slowly growing. Shave biopsy revealed that the horn was from a basal cell carcinoma. The patient was referred for Mohs surgery to excise the remainder of the cancer.
