description: "An acquired or congenital benign skin melanocytic neoplasm. It can occur on any area of the body, but most commonly occurs on the face of children and the thighs of young females. It is characterized by a proliferation of large spindle, oval, or large epithelioid melanocytes in the dermal-epidermal junction. The melanocytic proliferation subsequently extends into the dermis."
