A 51 year old woman was referred to dermatology clinic with multiple asymptomatic erythematus papules and plaques on her back, which she had developed over the previous 2 months ago. In the dermatological examination, there were multiple atrophic papules with hypopigmented centers and sharp borders on her back, some of which were annular with elevated violaceous borders (Figures 1, 2). Further observed were multiple purple, polygonal, shiny papules and plaques on her lower extremities. Mucosa was normal, and there was no nail change. The general physical examination was normal, and she had no family history of similar problems. An incisional biopsy was carried out on one of the atrophic papules.
