A 77-year-old white man presented with a 5-year history of a nonhealing, verrucous plaque on the distal aspect of his right forearm. He also had a history of coronary artery disease, congestive heart failure, and type 2 diabetes mellitus. Neither the patient nor his son could recall any trauma to the affected area. The plaque was asymptomatic except for occasional pruritus. Although the patient was relatively sedentary because of other health problems, he reported that he enjoyed gardening as a hobby.
