According to its original meaning, the term “nevus” has been applied to birthmarks. With regard to melanocytic nevi, the term “nevus” has lost its original meaning and is now being used for congenital and acquired proliferations of melanocytes. The evolution of nevi that are already visible at birth (large congenital nevi or garment nevi) cannot be studied because it is happening “in utero.” The term “tardive congenital nevus” has been applied to melanocytic nevi that are not visible at birth but have a clinical, dermatoscopical, and dermatopathological phenotype similar to nevi that are present at birth. They are significantly smaller than “true” congenital nevi and usually appear in childhood but may appear even as late as in puberty. Their evolution has been studied from an epidemiologic but also from a morphologic point of view [1–5].
