Moles (Nevi)
A mole, also known as a nevus (plural: nevi), is a very common skin growth. Moles develop as a result of clusters of melanocytes (pigment producing cells) in the skin. Although a mole can be present at birth (called a congenital nevus), most nevi appear during childhood and adolescence. Most people have between 10-40 moles. Moles can vary in size, shape, and color. Common moles are typically round or oval in shape.
