There are common warts, plantar warts, genital warts, and flat warts. Common warts usually grow on the fingers and hands. They are more common in areas of broken skin, such as where fingernails are bitten. Plantar warts grow on the soles of the feet and are difficult to eradicate. Genital warts are transmitted by sexual intercourse and occur on the male and female genitalia.
Flat warts are smoother and smaller than the other types of warts.
They grow in clusters, up to 100 in one area. Some children get them on the face. They are more common on women's legs and in the beard distribution of men. Sometimes they do. Other times they do not.
