[|Human|] Hello doctor, I have developed a darkish bruise like rash on my skin over my rib - on lower left side. This rash has been there for many years. It can become extremely irritated and itchy many times a day. The rash has progressed from a mild state of being a small reddish area to now a brownish leathery scaly area. I believe the change of appearance to be caused by the constant scratching to obtain relief from this irritation.
