Overview of Dysplastic Moles

Dysplastic nevus, also referred to as atypical nevus or Clark's nevus, is an acquired mole that may appear as solitary or multiple lesions. They are significant in that someone with a dysplastic nevus is considered to have an increased lifetime risk for melanoma.

Dysplastic nevi are seen in about 4 percent of the Caucasian population in the United States. Some families have large numbers of dysplastic nevi as well as histories of melanoma. These people must be observed closely because their lifetime risk for melanoma can be quite high.

Dysplastic Mole Cause

Dysplastic nevi are acquired and typically appear during puberty. The tendency to develop dysplastic nevi is familial.
