A melanocytic nevus (also known as nevocytic nevus, nevus-cell nevus, and commonly as a mole) [1] [2] is usually a noncancerous condition of pigment-producing skin cells. It is a type of melanocytic tumor that contains nevus cells . [ 2 ]
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. [5] Moreover, dermatologists have a standardized system for determining whether a skin lesion is suspicious for malignant melanoma.
The congenital melanocytic nevus is a type of melanocytic nevus (or mole) found in infants at birth. This type of birthmark occurs in an estimated 1% of infants worldwide; it is located in the area of the head and neck 15% of the time.
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.

Melanocytic nevi and neoplasms are caused by either a proliferation of (1) melanocytes, or (2) nevus cells, a form of melanocyte that lack dendritic processes.

An epithelioid blue nevus is a cutaneous condition most commonly seen in patients with the Carney complex. [7]: 701 A deep penetrating nevus is a type of benign melanocytic skin tumor characterized, as its name suggests, by penetration into the deep dermis and/or subcutis. Smudged chromatic is a typical finding.
