Dysplastic nevi. Their significance and management.

Dysplastic nevi are found in a significant percentage of the population and are a sign that an individual with these nevi has a greater risk for developing a melanoma than do individuals without them.

Guidelines for the care of patients with all forms of dysplastic nevi are outlined.
