Dysplastic Nevus (or atypical mole) is a mole that is different from a common mole. The distinctive appearance of an atypical mole generally includes irregular or indistinct borders, or non-uniform coloring that can range from pink to dark brown. Atypical moles can be found anywhere on the body, but are most common on the trunk. They are also usually larger than an ordinary mole and may be flat or raised.

The distinctive appearance of the mole is the most obvious indicator that it should be examined by a doctor. While dysplastic nevi themselves are benign, research by the National Cancer Institute can suggest that atypical moles may be more likely than ordinary moles to develop into melanoma, a malignant skin cancer. Most atypical moles will not become malignant, but they do have a higher risk than common moles. The more atypical moles a person has, the higher the risk of developing melanoma.

How do you treat Dysplastic Nevus?

Most Dysplastic Nevus (moles) do not require treatment. If treatment is needed because it is bothersome to the patient or they find it unattractive it can be removed in the office by a surgical excision or surgical shave.
