My child has a bump on his finger. How do I tell if it is a wart?

by Amy R. Beach, FNP

Common warts are generally found on the hands but can occur anywhere.  They often start as just a small bump but can quickly increase in size.  They are generally firm with a rough surface and may have black pinpoint spots.  Plantar warts occur on the feet.  They are usually flat and resemble a callous. Both types can be painful if irritated.  A diagnosis by your pediatrician is recommended.

Q:  What causes warts, and are they contagious?

A:  Warts, both common and plantar, are caused by a virus.  Because of this, they can be spread directly from person to person or indirectly by touching a towel or piece of clothing that an infected person used.

Q:  How are warts treated?

A:  Warts will sometimes resolve without treatment. However, if they are spreading or cosmetically are an issue, treatment can be considered. Plantar warts can be more difficult to treat as they can extend up deep into the skin.  Many home remedies and over-the-counter treatments are available.  For common warts, duct tape can be applied over the wart for a week.  After a week, the tape should be reomved and the wart should be thoroughly soaked in warm water. After soaking, the surface should be scraped with an emery board, and then the tape can be reapplied.  This method can be used until the wart resolves. If you try an over-the-counter method, look for one the contains 17% salycilic acid. When using these products, make sure only the wart is treated, or chemical burns can occur on the healthy skin surrounding the wart.  Also, soak and scrape the warts before each treatment.  If at any time, the wart becomes painful or inflammed, treatment should stop until the symptoms resolve. 

If home or OTC methods are not successful or the warts reoccur, more intensive treatment is available at your pediatrician’s office.

Q:  How can I stop warts from spreading?

A:  If you have warts, don’t pick at them. If they are around the nails, don’t bite your fingernails or use the same nail clippers on nails with warts and healthy nails.

If you don’t have warts, wear flip flops in public showers.
