Melanocytic nevi are benign hamartomas of the skin composed of nevus cells. They are almost always present in fair-skinned individuals and can arise in any anatomic site. When present at birth or during the first 2 years of life, they are categorized as congenital nevi. Melanocytic nevi that show up later in life are described as acquired nevi. The latter are further classified into common acquired nevus, dysplastic (atypical) nevus, blue nevus, Spitz nevus, and halo nevus. Their association with melanoma seems to depend on the total number and the specific types of melanocytic nevi. Regarding their benign nature, usually they do not require any therapeutic intervention. However nevi at special anatomic sites, atypical nevi, or nevi with an intriguing clinical-dermoscopic presentation should be followed up with dermoscopy in a more regular basis.
