Plantar Wart (Verruca Plantaris)

Plantar Wart (Verruca Plantaris)

Plantar warts (feet) and palmer warts (hands) are noncancerous skin growths, caused by a viral infection in the top layer of the skin.


On average, plantar warts are small growths on the foot, about the size of a pencil eraser. Some warts do grow larger and plantar warts can grow in clusters. Occasionally, a corn or callus may be mistaken for a plantar wart. Plantar warts can look different from Palmer warts because the skin on the bottom of the foot is much thicker than the skin on the back of the hand.

Risk Factors

Although the disease the causes plantar warts is spread from person to person through transmission of a skin virus, the risk of getting a hand or foot wart from another person is very small for most people. However, risks increase for people with compromised immune systems. The virus that causes plantar warts can be contracted through an abrasion, a skin puncture or cut.


Plantar warts are caused by the Human Papillomavirus or HPV. Many strains of the virus exist.  Although both are caused by HPV, the virus strain that causes plantar warts is not the same strain that causes genital warts.


Plantar warts may go away without treatment.  If treatment is required options include simply placing tape over the wart.  There are also over the counter treatment options.  However, because much of the mass of a plantar wart is below the surface of the skin, fully removing one can be difficult. In severe cases, doctors may use liquid nitrogen to freeze the wart, laser treatment or surgery to remove the wart.
