Warts are non-cancerous skin growths caused by a viral infection in the top layer of the skin. Viruses that cause warts are called human papillomavirus (HPV). Warts are usually skin-colored and feel rough to the touch, but they can be dark, flat and smooth. Warts vary in appearance depending on the part of the body where it is growing.
There are several different kinds of warts including:
- Common warts
- Foot (Plantar) warts
- Flat warts
Common warts usually grow on the fingers, around the nails 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. These are often called “seed” warts because the blood vessels to the wart produce black dots that look like seeds.
Foot warts are usually on the soles (plantar area) of the feet and are called plantar warts.. Plantar warts have a bad reputation because they can be painful, feeling like a stone in the shoe.
Flat warts are smaller and smoother than other warts. They tend to grow in large numbers – 20 to 100 at any one time. They can occur anywhere, but in children they are most common on the face. In adults they are often found in the beard area in men and on the legs in women.
Warts are passed from person to person, sometimes indirectly. The time from the first contact to the time the warts have grown large enough to be seen is often several months. The risk of catching hand, foot, or flat warts from another person is small.
What should you expect from wart treatment?
Sometimes it seems as if new warts appear as fast as old ones go away. This may happen because the old warts have shed virus into the surrounding skin before they were treated. In reality new “baby” warts are growing up around the original “mother” warts. The best way to limit this is to treat new warts as quickly as they develop so they have little time to shed virus into nearby skin. A check by your dermatologist can help assure the treated wart has resolved completely.
