Moles or nevi appear in both men and women. These are flat patches or small skin growths that are round or oval in shape and have regular contours. Their color can be brown, dark brown, blue or flesh-colored .
Some people have a very large number of moles: beyond 50, the risk of developing skin cancer is greater.
Moles are not pruritic (i.e. not itchy) or painful.
A distinction must be made between a mole and an atypical mole . This lesion is not cancerous but differs from the rest of the moles by its appearance: its dimensions are larger, its outlines are irregular and its multicolored hues . Areas exposed to the sun are more prone to the appearance of atypical moles.
