||Melanocytic nevi are benign tumors composed of nevus cells. They are rarely present at birth and usually appear in adolescence and early adulthood. Traditionally, melanocytic nevi are classified by the location of the nevus cells within the skin as either junctional, dermal, or compound.
It currently appears that nevi begin as junctional nevi, and then descend to become compound nevi and ultimately intradermal nevi. Nevocellular nevi are asymptomatic. If itching, tenderness, or change in pigmentation or growth occurs, the possibility of malignant change must be considered.
