I have a question about a patient I work with. She has papules with dark center on feet, legs, back, buttock, arms. She is on oral hydroxazine and said that helps the itching, but was also given a cream (she wasn't sure of name) that made her skin harder and darker. She has had 2 biopsies as the first she said they didn't know what it was and is awaiting results on the second one. Recently started on dialysis although she has had this several weeks before. Any thoughts? Also, she did mention one doctor thought possible lupus or some type of autoimmune disorder.
