I have to be truthful but I'm not all that good w/rashes & skin conditions, much less when they're being described - you know that saying about how much a picture is worth. The best advice I can offer you is to go see your family physician or a dermatologist and get evaluated. You don't mention how often/quickly your spot changes color but I'm always worried about melanoma. I suppose some sort of vascular lesion could change color more quickly depending upon blood flow. Sorry I couldn't be of more assistance. Good luck!
