Common warts (verruca vulgaris) are more of a nuisance than a serious health problem, but they are interesting. There is a whole mythology surrounding their cause (touching toads?) and treatment (everything from banana peels to vitamin C). Many people believe they can be made to vanish by suggestion or hypnosis. I used to believe that too.
Every doctor has wart stories. Here are some of mine.
- A patient made an appointment to see me because he had a wart, but when he tried to show me his wart he discovered that it had vanished! Apparently, just making the appointment cured it.
- Another patient did have obvious warts and I prescribed the “wart medicine” that our pharmacy tech compounded, based on salicylic acid. He was out of one of the ingredients and had to ask my patient to return in a week. When she returned, her warts were already gone. The wart medicine apparently worked so well that you didn’t even have to use it!
- I worked with a dermatologist who used a colorful laminated card with a picture of a toad to stroke children’s warts, telling them it was a wart remover. In his experience, this would frequently make the wart vanish over the next few days. Was this ethical? Was he lying and deliberately deceiving patients, or could this be excused as playing make-believe to distract the child and improve his attitude about the wart?
