A '''plantar wart''' is a [[wart]] caused by the [[human papillomavirus|human papilloma virus]] ([[HPV]]). It is a small lesion that appears on the sole of the foot (hence the name, from [[Latin]] ''planta pedis'', the sole of the foot) and typically resembles a cauliflower. A plantar wart may have small black specks within it that ooze blood when the surface is shaved; these are abnormal capillaries. Though the name ''plantar wart'' describes specifically HPV infection on the sole of the foot, infection by the virus is possible anywhere on the body and common especially on the palm of the hand, where the appearance of the wart is often exactly as described above for plantar warts. Because of pressure on the sole of the foot, a layer of hard skin forms over the wart. A plantar wart may or may not be painful. It can be spread in communal showers, around swimming pools, by sharing shoes, etc. | A '''plantar wart''' is a [[wart]] caused by the [[human papillomavirus|human papilloma virus]] ([[HPV]]).

Overview
A plantar wart is a wart caused by the human papilloma virus (HPV). It is a small lesion that appears on the sole of the foot (hence the name, from Latin planta pedis, the sole of the foot) and typically resembles a cauliflower. A plantar wart may have small black specks within it that ooze blood when the surface is shaved; these are abnormal capillaries. Though the name plantar wart describes specifically HPV infection on the sole of the foot, infection by the virus is possible anywhere on the body and common especially on the palm of the hand, where the appearance of the wart is often exactly as described above for plantar warts. Because of pressure on the sole of the foot, a layer of hard skin forms over the wart. A plantar wart may or may not be painful. It can be spread in communal showers, around swimming pools, by sharing shoes, etc.
Pathophysiology
The human papilloma virus types 1, 2, 4, or 63 are classified as clinical (visible symptoms). The virus attacks the skin through direct contact, entering through possibly tiny cuts and abrasions in the stratum corneum (outermost layer of skin). After infection, warts may not become visible for several weeks or months. Because of pressure on the sole of the foot, the wart is pushed inward and a layer of hard skin may form over the wart. A plantar wart may be painful. Warts may spread through autoinoculation, by infecting nearby skin or by infecting walking surfaces. They may fuse or develop into clusters called mosaic warts.
Causes
Plantar warts are benign epithelial tumors caused by infection by human papilloma virus types 1, 2, 4, or 63. All warts can spread from one part of your own body to another. They may spread from one person to another, but this is uncommon. Infection typically occurs on moist walking surfaces such as showers, swimming pools, or shoes. The virus can survive many months without a host, making it highly contagious.
Epidemiology and Demographics
It is estimated that 7-10% of the US population is infected. Plantar warts tend to affect only 0.29% of people who have never worn shoes.[1]
Treatment
Medical Therapy
No treatment in common use is 100% effective. The most comprehensive medical review found that no treatment method was more than 73% effective and using a placebo had a 27% average success rate.
Prevention
Although immunization is available for the HPV and strains causing cervical cancer and venereal warts, there is currently no vaccination treatment for plantar warts.
