What is a Plantar Wart?
A wart is a small growth on the skin that develops when the skin is infected by a virus. The virus may enter the skin through a weak area such as a tiny cut. These small growths can develop anywhere on the foot, but they most commonly appear on the bottom or weight bearing portions of the foot. Warts are typically caused by the human papilloma virus (HPV).
Types of Plantar Warts
There are two types of plantar warts:
- A solitary wart is a single wart. It often increases in size and may eventually multiply forming additional satellite warts.
- Mosaic warts are a cluster of several small warts growing closely together in one area. Mosaic warts are more difficult to treat than solitary warts.
Symptoms of Plantar Wart
- A small, fleshy, rough, grainy growth that is usually present on the bottom of your foot.
- Hard, thickened skin that may be mistaken for a callus.
- Pain when walking and standing. Squeezing the sides of the wart may also cause pain and is a key finding in the diagnosis of warts.
- Black pinpoint dots that appear on the surface of the wart or callused growth on your foot. The tiny dots are dried blood contained in tiny blood vessels called capillaries.
- A skin lesion that interrupts the normal lines or ridges in the skin on your foot.
