A mole, technically known as a<unk> , is a small, dark spot on human skin. According to the American Academy of Dermatology, the majority of moles appear during the first two decades of a person’s life while about one in every 100 babies are born with moles.  Acquired moles are a form of benign neoplasm, while congenitalmoles are considered a minor malformation, or hamartoma. A mole can be either subdermal (composed of melanin), or a pigmented growth on the skin, formed mostly of a type of cell known as melanocytes. The high concentration of the body’s pigmenting agent, melanin, is responsible for their dark color. Moles are a member of the family of skin lesions known as nevi.
