A wart is a growth in the skin caused by a viral infection. Warts tend to be hard and flat with elevated, rough surfaces, with or without well-defined boundaries. Some may often have one or more black pinpoints. They are frequently called plantar warts because they appear on the bottom, or plantar surface, or sole of the foot. Children, especially teenagers, tend to be more susceptible to warts than adults.

It is often possible that other benign lesions such as corns or calluses, or more serious lesions, such as carcinomas and melanomas, can be mistakenly identified as warts. Because of these identification problems, it is always best to consult a podiatrist regarding any suspicious growths or eruptions on the feet. If warts are left untreated, they can grow and spread into clusters.


Warts are caused by a virus, which typically invades through the skin through a small cut or abrasion.
