Plantar Warts Removal Treatment – Symptoms and Causes

What are Plantar Warts?

A plantar wart is a skin growth most commonly found on the bottom of the feet in teens, children, and the elderly that is caused by a virus infection – HPV (human papillomavirus). What does it look like? A solid grainy (bumpy) growth that appears on the bottom part of the ball of the foot, heels and toes, especially in areas that experience pressure. Plantar Warts can grow inward due to pressure: beneath a hard and thick layer of skin (callus area). Even though with time this infection may clear up on its own, a majority of patients desire faster relief. The main aim or treatment option available is to remove them completely.

What Causes Plantar Warts?

Plantar wart (scientifically known as Verruca Plantaris) is caused by an infection related to the human papillomavirus located on the outer layer of the skin. Due to wart’s position, one is going to feel pain when pressure is applied while they are either standing or walking. The virus will enter the body through breaks, cuts or any other weak spot at the bottom part of the feet.

Lesions can appear in single (one) or cluster (many) – known as mosaic warts. If they appear in the cluster (mosaic warts), treatment becomes a bit more difficult to treat and remove them.

How Is The Virus That Causes Plantar Warts Transmitted?

Just like it is with any disease or health condition, different people react differently to HPV. As such, it is important to note that not everybody who comes into contact with the virus will develop wart. At the same time, some will develop severe problems when they come into contact with the virus. Therefore, it is important to note that every person will react differently to the virus even those in the same family.

It is also important to note that HPV that causes Plantar Warts are not contagious. Therefore, the virus is not easily transmitted through direct contact from person to person. The virus flourishes in warm, moist environments. You may contact the virus through walking around in public locker rooms, showers, or swimming pools. If the virus spreads from one part that has been infected, more warts could appear.

Someone cannot be infected if the virus has no point of entry. For the virus to get into your body, the skin must have a point of entry. It could enter your skin if:

  • Dry skin cracks in your feet
  • Scrapes and/or cuts
  • Soft, wet, fragile skin from being in the water for a long time.

After diagnosis by your podiatrist, the next course of action is treatment. If the condition is painful, your foot doctor will schedule an appointment or start treatment right away. The truth is that some warts go away without the need of treatment. However, the only limitation is that it will take a year or several years depending on your immune system to go away. At the same time, rather than them going away by themselves, it may spread to other areas causing more pain. Note – You could require repeated treatments before they go away. Moreover, they could return later.

Conservative Treatment for Removing Warts

Dr. Jarman is very conservative with wart removal and treatment options and elects not to cut or burn (freeze) them out. His preference is to use Cantharidin, a topical treatment that provides little discomfort with application and is very successful. This method works great for children and squeamish adults.

What is Cantharidin?

Cantharidin is a topical ointment used since the 1950’s to treat and remove warts and benign molluscum skin lesions.

Where does Cantharidin come from?

The “Spanish fly” blister beetles produce Cantharidin, a blister agent that is harvested for chemical use. The male species discharges Cantharidin when mating, passing the substance to the females that make use of the chemical liquid substance to cover her eggs to defend against any predators.

How does Cantharidin work?

Cantharidin (a blistering agent) works on the epidermis (your skin’s outer layer) cell membranes. With a topical application, it causes a blistering effect to breakdown the top layer of the skin cells to get to the wart. The blister in turn causes the tissues that contain the plantar wart virus to separate away from the skin. For this reason, with proper use the area usually heals without scarring.

After Cantharidin Treatment: If changes or response to treatment is not observed by the doctor, further analysis may be required. In this case, the doctor may use a biopsy to rule out other potential causes for the growth. No matter what the treatment approach used, it is paramount to follow the doctor’s instructions. It may include home care medication and treatment. If the condition persists, consult your foot doctor again, because it could be another problem.

We included a few clinical images taken by Dr. Jarman of a patient’s foot (two weeks after application of Cantharidin) that show exactly how deep warts go into the skin. This method of treatment is very successful compared to the ineffective over-the-counter products for wart removal.
