A 60-year-old woman went to the doctor after noticing sudden onset of extremely painful, dark areas that had developed on her legs over the course of a few days. On examination, there were violaceous and dark brown, retiform plaques, some depressed and some crusted, over the legs. The patient had a history of diabetes, hypertension, and chronic renal insufficiency for which she required hemodialysis.
