Overview

Melanocytic nevus is a type of melanocytic lesion. Depending on the degree of cytologic atypia it can be classified into mild, moderate or severe.

Classification

Most dermatologists and dermatopathologists use a system devised by the National Institutes of Health (NIH) for classifying melanocytic lesions. In this classification, a nevus can be defined as benign, having atypia, or being a melanoma.

A benign nevus is read as (or understood as) having no cytologic or architectural atypia.
An atypical mole is read as having architectural atypia, and having (mild, moderate, or severe) cytologic (melanocytic) atypia.^[1]^[2]
