A 65-year-old woman presented with a slowly spreading, asymptomatic, purpuric eruption on the fourth finger web of the left hand (Figure 1) and a 3-year history of hypertension, for which she had been taking amlodipine camsylate (Amodipine) (10 mg/d). Her eruption had developed over a period of about 5 months. She had no history of skin lesions or trauma. The lesions consisted of dark-red, purpuric macules and papules. A 3-mm punch biopsy specimen was obtained from a macule, and the histopathologic findings are shown in Figure 2.
