Warts are typically small, rough, hard growths that are similar in color to the rest of the skin. They typically do not result in other symptoms, except when on the bottom of the feet, where they may be painful. While they usually occur on the hands and feet, they can also affect other locations. One or many warts may appear.

The archetypal witch of western culture is often associated with warts. Most toad species have dry skin with bumps which in popular culture are called warts (although they really are glands).
