A 61-year-old Japanese woman was referred to us with a 6-month history of gradually spreading, asymptomatic, irregularly shaped, red-brown purpuric papules and plaques with tiny petechiae on her left lower abdomen, back, and femoral regions (Figure 1). The lesions had a zosteriform distribution of L1/L2. She had no history of a bleeding disorder, and the medical and family histories were unremarkable.
