Warts are small skin growths. Most are harmless and painless. They can appear on any part of the body.

Signs & Symptoms

•  Common warts. These are firm and often have a rough surface. They are round or have an irregular shape. They are found on places subject to injury, such as the hands, fingers, and knees. Common warts are flesh-colored to brown. They may spread, but are not cancer.

•  Flat warts. These are smooth and flesh-colored. They are found mainly on the hands and face and may itch.

•  Plantar warts. These occur on the soles of the feet. They look like corns or calluses and may have little black dots in the center. They can be painful.

•  Digitate warts. These threadlike warts grow on the scalp.

•  Filiform warts. These are long, narrow, small growths. They appear mainly on the neck, eyelids, or armpits.

•  Genital warts. See Sexually Transmitted Infections (STIs) – Human Papillomavirus (HPV).


Warts are caused by human papillomaviruses. One of these viruses may enter the body through a cut or nick in the skin. Scratching or picking at warts may spread them to other sites. Some persons are more prone to getting warts than others. People who cannot fight off disease are also more at risk for warts. You cannot get warts from frogs or toads.





Treatment for warts depends on their location, type, and severity and how long they have been on the skin. About 50% of warts go away in 6 to 12 months without treatment.


Self-care measures can be used for warts not on the face or genitals. Medical treatment includes liquid nitrogen, chemical injections, topical medicines, laser surgery, and minor surgery.
