i had a small purplish brownish spot show up on my shift in the middle of December. It hasn't changed color or size since I noticed it. I did try scratching it and it looked like a scab came off. I will enclose a few photos to see if you guys can point me in the right direction.
Probably needs a photo taken a little further away. But next to the area you ask about is something that looks like a wart too.
