In the dermal nevus all of the melanocytes are in the dermis. Dermal nevi are clinically manifested as pale soft wrinkled polyps on the skin. This sequence is the normal life pattern of a nevus. Dermal nevi can eventually drop off the skin. Dysplastic nevi do not follow this pattern of maturation and self-destruction. If melanoma does develop, it typically begins in a new spot on the skin and not from the dysplastic nevus itself. Most Americans (about 332 million people) have common moles. It can develop from a common mole or dysplastic nevus, but more often it develops in an area of apparently normal skin. Because the primary significance of atypical moles is their association with melanomas, the ABCDE (asymmetry, border irregularity, color unevenness, diameter of 6 mm or more, evolution) mnemonic13 is a valuable tool for clinicians and patients to identify suspicious lesions. People with XP have a high risk of developing melanoma and other skin cancers when they are young, especially on sun-exposed areas of their skin. A mole may be a sign of skin cancer if it has irregular borders or an asymmetrical shape or if it changes in color, shape, size or height. Because of the increased risk of melanoma, patients with atypical moles should be screened for melanoma, typically yearly, although the optimal methods and timing have not been determined. There is some evidence to suggest an increased melanoma yield based on photographic change in lesions that were not strongly suspected to be melanoma by appearance alone.13,14 Magnified evaluation of atypical moles with dermoscopy can be helpful in identifying lesions that merit biopsy, although outcomes are dependent on the skill of the operator.13,25,27 A recent review of dermoscopy published in American Family Physician is available at https://www.aafp.org/afp/2013/1001/p441.html.
