PY - 2019 T2 - The Color Atlas and Synopsis of Family Medicine, 3e AB - A 90-year-old woman presents with a hard keratotic papule on the right cheek that has grown over 6 months. It is tender to the touch and has a pink base (Figure 176-1). A shave biopsy through the base is consistent with a cutaneous horn derived from a well-differentiated squamous cell carcinoma (SCC). The patient undergoes an elliptical excision at the base of the horn in the office for definitive therapy.
