Overview
Atypical moles (atypical nevi) or dysplastic moles (dysplastic nevi), are caused by collections of the color-producing (pigment-producing) cells of the skin (melanocytes) in which the cells grow in an abnormal way. Atypical moles may occur as new lesions or as a change in an existing mole. Lesions may be single or multiple. In atypical-nevus syndrome, hundreds of atypical moles may be seen. People with atypical moles may be at increased risk for developing skin cancer (melanoma), with the risk increasing with the number of atypical moles present.
