- dysplastic nevus
- listen (dis-PLAS-tik NEE-vus)
A specific type of nevus (mole) that looks different from a common mole. Dysplastic nevi are 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 (a type of skin cancer), and the more dysplastic nevi a person has, the higher the risk of melanoma. A dysplastic nevus is sometimes called an atypical mole.
