Found this on husbands back today. The mole isn't new but the ring around it is. It could have only been there a few weeks at most I'm guessing. He also has a petechai like rash on his back from sweating due to the hot weather and him being sat in a leather chair for work all day.
He thinks it might be ring worm, I'm not sure if ring worm would be around a mole? I'm starting to panic and think the worst. Anyone have anything similar? Obviously will go to see a dr on monday.
