Overview
Dysplastic 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]
