The appearance of a wart depends on where it is growing.
Warts are usually skin colored and feel rough to the touch, but can be dark, flat or smooth.
Genital warts Common warts usually grow around the nails, on the fingers and on the backs of the hands. They are more common where skin has been broken, for example where fingernails are bitten or hangnails picked. Foot warts are usually on the soles of the feet and are called plantar warts. When plantar warts grow in clusters they are known as mosaic warts. Most plantar warts do not stick up because the pressure of walking flattens them and pushes them back into the skin.
