Nevophobia

Naevophobia (from Latin naevus, "skin mole") is the fear of moles on skin. Moles are small darker spots on the skin that can be unpleasant looking to some, which is a common fear trigger. Naevophobes would not look at people's skins as seeing moles may make them dread or even panic in shock. They can look at the skins themselves if they're familiar and don't have moles on them. More severe sufferers would cover all of the skin as moles can appear anywhere at anytime while wanting moles to be removed by seeing a doctor.
