A dysplastic nevus is also referred to as an atypical or Clarks nevus and has been the topic of much debate in the fields of dermatology and dermatopathology. It is an acquired mole demonstrating a unique clinical and histopathologic appearance that sets it apart from the common nevus. These moles appear atypical clinically, often with a fried-egg appearance, and are commonly biopsied by providers due to the concern for melanoma.

Dysplastic nevus, also called atypical or Clark nevus, can be precursor to melanoma, as the observation that 36% of melanomas have dysplastic nevi near the invasive tumor supports. Signs that a dysplastic nevus may have transitioned into a melanoma include asymmetry in contour, a noticeable increase in pigment variations, or a grayish tint indicating regression. These malignancies typically arise at a younger age (mid-thirties), are sometimes multiple, and are often found on the trunk. Molecularly, dysplastic nevi have a profile intermediate between benign nevi and malignant melanoma. While there is a recognized connection between dysplastic nevi and melanoma, it’s crucial to note that only about 20% to 30% of melanomas evolve from preexisting nevi. Given that the majority of dysplastic and typical nevi do not develop into melanoma, preventive removal of melanocytic nevi is not typically advised.

A melanoma is a tumor produced by the malignant transformation of melanocytes. Melanocytes are derived from the neural crest; consequently, melanomas, although they usually occur on the skin, can arise in other locations where neural crest cells migrate, such as the gastrointestinal tract and brain. The five-year relative survival rate for patients with stage 0 melanoma is 97%, compared with about 10% for those with stage IV disease.
