Warts are growths on the skin caused by the human papillomavirus (HPV). They are very common, particularly in school-age children. Warts can spread by direct contact to other parts of the body, or to others. They are painless unless they appear on the soles of the feet. Warts are sometimes described by their appearance or location:
• Common warts (verruca vulgaris) can appear anywhere on dry skin, but they are more commonly seen on the hands. They can appear in clusters.
• Flat warts are often on the face or legs. They are smaller and can be difficult to see.
• Plantar warts (foot warts) are located on the soles of the feet. The weight of the body pushes them into the deeper tissues, which can make them painful.
Laser removal is a safe, effective treatment for warts. The laser turns the area black for 10-14 days but doesn't cause an open wound. While it is possible to eliminate warts after just one treatment, it is more common to require a few treatments for successful removal.
