Plantar warts

Plantar warts are a common type of wart that specifically occur on the soles (or plantar surface) of the feet. Unlike other warts, plantar warts grow into the skin, not out of it, due to the pressure exerted on the soles of the feet. They are caused by the human papillomavirus (HPV), a virus that can be contracted from surfaces such as the floor of a public shower or locker room.

Causes

Plantar warts are caused by an infection with HPV. There are more than 100 types of HPV, but only a few cause warts on the feet. The virus attacks the skin through direct contact, entering through tiny cuts or abrasions on the plantar area. The risk of getting plantar warts is increased by direct contact with the HPV virus and is often contracted in public places like showers, swimming pools or locker rooms.

Symptoms

Plantar warts are often rough and spongy, and most are gray or brown with a center that appears as one or more pinpoints of black. They can be painful when pressure is applied either from side to side or directly on the wart, especially when walking or standing.

Treatment

Treatment for plantar warts varies depending on their size and location on the foot. Over-the-counter treatments include salicylic acid and cryotherapy. Prescription treatments include stronger salicylic acid or cryotherapy, immunotherapy, minor surgery, and laser treatment. It is important to note that even with treatment, warts can recur or spread to other areas of the body.

Prevention

Prevention of plantar warts can be achieved by avoiding direct contact with HPV, which includes not walking barefoot in public places, changing shoes and socks daily, keeping feet clean and dry, and avoiding contact with warts on other parts of the body or on the bodies of others.
