What are warts?

Warts are non-cancerous skin growths caused by the papillomavirus. Warts are more common in children than adults, although they can develop at any age. Warts can spread to other parts of the body and to other persons. There are many different types of warts, due to many different papillomavirus types (more than 60). Warts are not painful, except when located on the feet. Most warts go away, without treatment, over an extended period of time.

Common types of warts:

The following are the more common types of warts:

Common warts

growths around nails and the back of hands; usually have a rough surface; grayish-yellow or brown in color

Foot warts

located on the soles of feet (plantar warts) with black dots (clotted blood vessels that once fed them); clusters of plantar warts are called mosaic; can be painful

Flat warts

small, smooth growths that grow in groups up to 100 at a time; most often appear on children's faces

Genital warts

grow on the genitals and are occasionally sexually transmitted; are soft and do not have a rough surface like other common warts

Filiform warts

small, long, narrow growths that usually appear on eyelids, face, or neck


Treatment for warts:

Specific treatment for warts will be determined by your physician based on:

your age, overall health, and medical history
