What Does a Mole Look Like?
A common mole (nevus) is a small growth on the skin that is usually pink, tan, or brown and has a distinct edge.
A dysplastic nevus is often large and does not have a round or oval shape or a distinct edge. It may have a mixture of pink, tan, or brown shades. People who have many dysplastic nevi have a greater chance than others of developing melanoma, a dangerous form of skin cancer. However, most dysplastic nevi do not turn into melanoma.
If the color, size, shape, or height of a mole changes or if it starts to itch, bleed, or ooze, people should tell their doctor. People should also tell their doctor if they see a new mole that doesn't look like their other moles.
The photos below show the difference between common moles and dysplastic nevi.

A common mole is usually small. The first photo shows a common mole that is less than 5 millimeters (about 1/4 inch) wide. The second photo shows small moles on a person's back. |
Dysplastic nevi are often larger than 5 millimeters wide. The first photo shows a large dysplastic nevus. The second photo shows several large dysplastic nevi circled on a person's back. |
