I've had 2 freckles on the sole of my foot for as long as I can remember (probably born with them) and they are the same as always, but last year I had a new one appear just above the others. It looks very similar, but is just a bit smaller and looks deeper I guess - this is also something that worries me a bit, although I think it's just because the skin in that area of the foot is very thick so it appears to be under many layers of skin. Anyway, it's been there for about a year (if not more) with no changes, and i was worrying it could be acral melanoma. However, this cancer is very aggressive, so I assume even if it was in the early stages, after a year it would at least somewhat change, even slightly. I'm obviously prone to these freckles on the sole of the foot so it may be normal for me, and I've seen photos of acral melanoma and they they are all quite dark in colour, whereas the new freckle is a much lighter shade of brown. It is also quite rare so even more unlikely.
The new one also appeared after summer - lots of time at the beach/pool, and I guess when you are lying down at the beach the soles of your feet are exposed, so it could just be that?
If anyone has seen what acral melanoma looks like, does this sound like it?
