A 79-year-old white woman presented for evaluation of hyperkeratotic nodules and plaques on the lower part of her left leg. The lesions had been present for approximately 5 to 7 years. The lesions had rapidly increased in both size and number over a period of several months. A skin biopsy specimen that had been obtained at an outside institution was interpreted as well-differentiated squamous cell carcinoma (SCC), prompting the patient's referral to our institution for treatment.
