PLANTAR AND FOOT WARTS

 

Started like a pimple but now looks like cauliflower growing on your feet? This is likely a viral infection known as a plantar wart.

 

                            

 








Plantar warts are benign (noncancerous) growths that occur on the sole (plantar surface), heel, or ball of the foot. Pressure from standing and walking often causes them to grow into deep layers of the skin. The human papilloma virus (HPV) causes several different types of warts, which are the most common type of skin infection. In some cases, the HPV virus dies within 1 or 2 years, and warts simply disappear. Podiatrists may recommend having plantar warts removed because they often are irritating and painful. Anyone can contract the virus that causes plantar warts. Plantar warts occur most often in children and young adults between the ages of 12 and 16. Incidence is higher in people who share common bathing areas (e.g., dormitory students, gym members).



 Plantar warts can occur when HPV invades the body through tiny cuts or breaks in the skin on the bottom of the feet. The virus often is encountered on contaminated surfaces, such as the tile floors of public locker rooms, showers, and swimming pools. Normally, antibodies in the blood destroy HPV, but in some cases, it takes refuge in the skin and causes plantar warts. Some people are more prone to the virus that causes plantar warts than other people. Risk factors include repeated exposure (e.g., walking barefoot in public locker rooms and common bathing areas) and having a weakened immune system. 



 Plantar warts usually are rough and spongy, and most are gray, brown, or yellow with dark pinpoints (tiny capillaries that supply blood to the wart). Scraping a wart may cause it to bleed. A plantar wart is similar in structure to an iceberg-the part on the surface of the skin is a small part of the entire anomaly. Often, the portion of the wart under the skin is at least twice as big as the part you can see.  Plantar warts may cause pain on the bottom of the foot. Patients often feel a "lump" on the bottom of the foot when standing, similar to having a stone in the shoe. In many cases, pressure from standing and walking prevents plantar warts from rising above the skin surface. If left untreated, plantar warts can grow up to 1 inch in circumference and may spread into clusters (called mosaic warts). In severe cases, they cause a change in gait or posture that results in leg or back pain.

Treatment


We have several practical and effective treatment options in clinic for plantar warts. Treatment regimens range from applications of safe, powerful medications applied to the warts in clinic to shrink the wart and kill the blood vessels (black dots within the warts), to at home regimens with prescritiption medications.


In the case of stubborn warts where conservative treatment has failed, surgical techniques are available. The most popular is autoimmune inoculation/ needling treatment. This unique therapy involves depositing a small amount of the virus into the deeper layers of the dermis, which activates the immune system.

Once the immune system is activated it usually requires four to eight weeks for the virus to be eradicated. Typically one treatment is required. Once the immune system is activated, it will target the virus anywhere on the body. For example: if there are warts on the other foot or hands, they too will disappear.
