A 30-year-old man presented with a 2-week history of an extensive pruritic and painful eruption that began on his palms and, over 4 days, spread to involve his extremities, trunk, and face. He had no significant medical history or history of skin disease. There were no systemic complaints, except for mild arthralgias. Physical examination revealed right axillary lymphadenopathy and numerous edematous, erythematous, and violaceous plaques arranged in solitary, annular, and double-ring configurations (Figure 1).
