Nevus of the left neck.
Symmetrical melanocytic compound lesion with shoulder formation (lateral spread of junctional component over dermal component). Unsharp demarcation (lateral demarcation of junctional component by single cells instead of nests). Slight pleomorphism and atypia of single junctional melanocytes. Fusion of rete ridges. Subepidermal lamellar (stacked) fibroplasia parallel to epidermis. Cytologically bland dermal component showing maturation and lacking mitotic figures. Scarce chronic inflammation of the demis with scattered melanophages.
