Hi there, I have a small dark spot about a millimeter or two in diameter that is almost perfectly circular with a pore hole in the middle. It does not itch or really even hurt to touch, has no hair growing out of it.. but has been there for the last few months and gotten a little darker as time progresses. I do have a picture I could show but there is nowhere to post one on here.. I am wondering if this is a mole I could be concerned about?
