Warts located on the hands are most commonly seen around the nails and cuticles, especially in children who bite their nails or pick at hangnails. Warts on the sole of the feet are known as plantar warts. They grow inward instead of outward on areas that exert pressure or bear weight. These inward growing warts can also occur on the palms of the hands. People who sweat heavily and who walk or exercise frequently are susceptible to them.
Flat warts are smaller and smoother than hand and foot warts.
They grow in clusters of 20 to 100 at a time in the beard area of men and on the legs of women. Genital warts are very contagious and occur on the genitalia, around the anus, and within the rectum. In women, they are also found inside the vagina and on the cervix. Genital warts are hard to treat and some are associated with cancer of the cervix. Both sexual partners should receive medical care.
