A 53-year-old black man presented with a 1-month history of large annular pruritic plaques on his trunk and extremities. The plaques had raised, violaceous borders and dusky, depressed centers, through which superficial dermal blood vessels could be readily visualized. Some of the plaques were confluent and rather extensive (Figure 1). The patient’s hair, nails, and mucosal surfaces were normal. His medical history was unremarkable, and he was taking no medications.
