Blue nevus refertur ad globum cutis incrementorum melanocytarum ex nimio incremento, qui caerulei ad nigras labefactat in capite, brachiis vel clunibus apparens. Solent esse solitaria et acquisita, sed etiam a nativitate praesens esse et in pluribus locis fieri possunt. Hae laesiones saepe confunduntur cum incrementis pigmentatis veluti melanomatis obscurioribus; typice apparent in cute, brachiis, dorsis inferioribus vel clunibus.
