My husband found a large area on my back a few days ago. It looks like an area about 6 inches long and 3 inches wide, but splotchy. It is dark brownish bloack, not raised, no itchy, no leisions. I had a derma check last Oct. and had 3 moles removed but this was not there. Does anyone have any suggestions as to what this is. I can't get a doctor appt. until next week. This is really scary.
