Warts are one of several soft tissue conditions of the foot that can be quite painful. They are caused by a virus, which generally invades the skin through small or invisible cuts and abrasions. They can appear anywhere on the skin, but, technically, only those on the sole are properly called plantar warts.

Children, especially teenagers, tend to be more susceptible to warts than adults; some people seem to be immune.

Identification Problems

Most warts are harmless, even though they may be painful. They are often mistaken for corns or calluses—which are layers of dead skin that build up to protect an area which is being continuously irritated. The wart, however, is a viral infection.

Plantar warts tend to be hard and flat, with a rough surface and well-defined boundaries; warts are generally raised and fleshier when they appear on the top of the foot or on the toes. Plantar warts are often gray or brown (but the color may vary), with a center that appears as one or more pinpoints of black. It is important to note that warts can be very resistant to treatment and have a tendency to reoccur.

Causes of Warts:

• Walking barefoot on dirty surfaces or littered ground where the virus is lurking.
• The causative virus thrives in warm, moist environments, making infection a common occurrence in communal bathing facilities.
• If left untreated, warts can grow to an inch or more in circumference and can spread into clusters of several warts; these are often called mosaic warts.
• Like any other infectious lesion, plantar warts are spread by touching, scratching, or even by contact with skin shed from another wart. The wart may also bleed, another route for spreading.
• Occasionally, warts can spontaneously disappear after a short time, and, just as frequently, they can recur in the same location.

Prevention:

• Avoid walking barefoot, except on sandy beaches.
• Change shoes and socks daily.
• Keep feet clean and dry.
• Check children's feet periodically.
• Avoid direct contact with warts—from other persons or from other parts of the body.
• Do not ignore growths on, or changes in, your skin.
• Visit your podiatric physician as part of your annual health checkup.

Treatment

• Medication – Including commercially prepared and prescription preparations to be applied at regular intervals as specified by your FDFAC physician.
• Surgery – Excision is usually required when nonsurgical treatments fail.
• Self Treatment - Generally not advisable. Over the counter preparations contain acids or chemicals that destroy skin cells, and it takes an expert to destroy abnormal skin cells, (warts), without also destroying surrounding healthy tissue.
