Dysplastic Nevus (Clark's Nevus)

Mostly flat and often larger than common moles and have borders that are irregular. A dysplastic nevus can contain different colors, which can range from pink to dark brown. Parts of the mole may be raised above the skin surface. A dysplastic nevus may develop into melanoma, and the more dysplastic nevi a person has, the higher the risk of melanoma. A dysplastic nevus is sometimes called an atypical mole.
