Warts and verrucas are small, non-cancerous growths within the skin caused by the human papilloma virus. Warts may occur
on their own or in clusters. There are many different types including:
- Common warts. These raised growths with a hard uneven surface are the most familiar type of wart, which usually appear
on the hands and feet.
- Plantar warts, known as verrucas. These are warts on the soles of the feet that have been pushed into the skin surface
by the weight of the body.
- Plane warts. These are smaller and lie flatter in the skin mostly on the hands or face.
Causes
They're caused by a viral infection in the skin cells. Warts are common and all children are vulnerable, but children with
immune system problems may have an increased risk. The virus is found throughout the environment and is highly infectious.
Symptoms
Each wart forms a small lump, but sometimes multiple warts, common warts are rarely painful, but plane warts may be itchy.
Verrucas form round areas within the skin, often with a central dark spot. They may be painful when pressure is applied.
Treatment
Most warts disappear without treatment after a few months. Warts and verrucas only need treatment if they're painful, or
are a cosmetic problem. There are a range of treatments that can be applied at home, which include a combination of salicylic
acid paint and rubbing with a pumice stone or foot scraper. Stronger treatments can be obtained from a chiropodist or doctor,
they include laser or cryotherapy (freezing), or surgical curettage to scrape it out. These treatments are quite effective,
but may need to be repeated. Very resistant warts can be injected with toxic chemicals.
