REPORT OF A CASE  A 21-year-old man from Yemen presented to the dermatology clinic with violaceous, depressed areas that had been increasing in number and size over the past 8 years. The depressions began on his trunk and had spread to his extremities. The patient was upset by the cosmetic appearance of the lesions, although he denied pain or pruritus. He stated that the depressions often developed small, indurated, white areas that gradually softened and darkened. None of the depressed areas had resolved over the past 8 years. The patient denied respiratory or gastrointestinal symptoms and was otherwise in good health.On physical examination, the patient was noted to have large, confluent, symmetrical depressions on the trunk, arms, and legs. The face, mucous membranes, palms, and soles were not involved. The violaceous depressed areas were sharply demarcated with a "cliff-drop" border (Fig 1). A lilac ring was not seen around
