An atypical mole may also be referred to as an atypical melanocytic nevus, [2] atypical nevus, B-K mole, Clark's nevus, dysplastic melanocytic nevus, or nevus with architectural disorder. [ 3 ] Dysplastic nevi often grow to larger than ordinary moles and may have irregular and indistinct borders.
However, a melanocytic nevus is benign, and melanoma is malignant. Most melanocytic nevi never evolve into a cancer, with the lifetime risk for an individual nevus being 1 in 3000 for men and 1 in 11 000 for women.
