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.
The typical wart is a raised round or oval growth on the skin with a rough surface. Compared with the surrounding normal skin, warts may appear light, dark, or black (rare). Most adults are familiar with the look of a typical wart and have little trouble recognizing it. Unusual warts with smooth surfaces or flat warts in children may be more difficult for parents to recognize. Common warts tend to cause no discomfort unless they are in areas of repeated friction or pressure. Plantar warts, for example, can become extremely painful. Large numbers of plantar warts on the foot may cause difficulty walking or running. Some warts will disappear without treatment, although it can sometimes take a couple of years. Treated or not, warts that go away often reappear. All warts can spread from one part of your own body to another. Unsightly or painful warts can be treated. Warts around and under your nails are much more difficult to cure than warts in other places.
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.
Epidemiology and Demographics
It is estimated that 7-10% of the US population is infected. 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.[1]
