A plantar wart is a solid, firm growth with a grainy texture caused by the human papillomavirus that commonly develops on the bottom of the foot, according to Mayo Clinic. The warts develop when the virus enters the skin of the foot through broken skin or cuts.
The two types of plantar warts are solitary warts and mosaic warts, explains Foot Health Facts. A solitary wart consists of a single growth that may grow larger or multiply. Mosaic warts consist of a clustered group of small warts that grow adjacent to one another. Plantar warts resemble calluses and are often speckled with black dots. Individuals with plantar warts may also experience pain upon walking or standing.
In many cases, plantar warts resolve on their own over time, but the condition can recur if the warts are not fully removed, explains Cleveland Clinic. Since plantar warts can cause significant pain, it is also common for sufferers seek immediate treatment. Treatments for plantar warts include topical medications that cause a blister to form over the warts and pull them out, liquid nitrogen treatments that freeze the warts off, chemical peels that pull the skin off in layers, and laser treatments. Individuals can minimize their risk of contracting the plantar wart virus by wearing protective footwear in shared environments, such as locker rooms and public showers, as well as avoiding contact with individuals who have plantar warts.
