Warts are benign skin growths that appear on the skin when a virus infects the top layer of the skin. Viruses that cause warts are called human papillomavirus (HPV). Wart viruses are contagious. Warts can spread by contact with the wart or something that touched the wart.
Common Warts are warts that usually appear on hands or face. They appear as small, fleshy, grainy bumps and are flesh-colored, white, pink, or tan. They are rough to the touch and can be sprinkled with black pinpoints, which are small, clotted blood vessels. These warts can spread from the hands to the face through touching.
Plantar Warts are warts that grow most commonly on the surface of the feet. These warts can grow in clusters and are often flat or grow inward.
