Plantar Warts

Plantar Warts are growths on the soles of the feet. They are often mistaken for corns or calluses, but they are different because they are caused by a virus. They grow in clusters and are usually flat. Like other warts, they contain black dots. Although most Plantar Warts are harmless, they can be very painful.

Causes

Plantar Warts are caused by the human papillomavirus (HPV), which can be contracted by walking barefoot on unsanitary surfaces. Touching and scratching can cause the virus to spread.

Risk Factors

A risk factor is something that increases your chance of getting a disease or condition.
  • Exposing your feet to unsanitary surfaces
  • Age: Children and teens
  • Having a suppressed immune system due to:
    • AIDS
    • Lymphoma
    • Immunosuppressive drugs
  • Atopic dermatitis (eczema)

Symptoms

Symptoms include:0
  • Hard, flat growths on the soles of the feet
  • Pain in the area of the warts

Diagnosis

The doctor will ask about your symptoms and medical history, and examine your feet. You may be referred to a doctor who specializes in foot problems (podiatrist) or skin disorders (dermatologist).

Treatment

Because Plantar Warts tend to recur, it's best to see a doctor for treatment, rather than to try to treat the warts yourself with over-the-counter preparations.
Treatments include:
Acid – applying a mild acid to disintegrate the warts
Cryotherapy – freezing the warts to kill the virus
Laser Treatment – using a laser to kill the virus
Electrocautery Treatment – burning the wart
Surgical Removal – cutting out the warts (with anesthetic)

Prevention

The best ways to prevent Plantar Warts is to keep your feet from coming into contact with the virus that causes them. Ways to do this include:
  • Avoid walking barefoot, except on sandy beaches.
  • Wear plastic sandals when showering in public bathrooms.
  • Change your shoes and socks daily.
  • Keep your feet clean and dry.
  • If you have children, check their feet periodically.
  • Avoid direct contact with warts, either from other people or from other parts of the body.
