Freckle

Also called �ephelis�, plural �ephelides,� a small, brownish, well-circumscribed, stainlike spot on the skin occurring most frequently in red- or sandy-haired individuals. In genetically predisposed individuals who have been exposed to the ultraviolet radiation of sunlight, production of the pigment melanin increases in the pigment cells of the skin (melanocytes); the number of melanocytes does not increase.
