Medical term for a spot on the skin, such as a mole. A mole is a cluster of melanocytes that usually appears as a dark spot on the skin.
a lesion of the skin that may be present from birth, but most often appearing later in life. By three years of age, 40% of children will have at least one nevus. Some varieties of nevi are hereditary – that is, they "run in the family". Most nevi are pigmented, but some are not. A common nevus in light-skinned people (usually called a mole) is typically small, round, tan or brown, with a smooth border, and exactly the same throughout. The brown color in the nevus is melanin. Other types of moles may be very large, or have irregular borders. There are dozens of different types of nevi, of many shapes, colors and sizes. While most nevi are benign, malignant changes can occur to turn the benign nevus into a melanoma. (Click on View Moles to view photographs of normal moles).
