Hello, I've had these strange pinkish/brownish marks on my chest and back for a few months now, and they won't seem to go away. They do not hurt, it is the appearance that bothers me. They actually do not physically hurt me any way, but they flake when I scratch them, but never go away. I do not live in an extremely sunny place, and am not regularly exposed to sunlight. They range in different sizes, some large and some small. By large, it is about the size of an English 2 pence coin. They have no real shape except for being irregular and circular. Please help.
