Common warts are local growths in the skin that are caused by human papillomavirus (HPV) infection. Although they are considered to be contagious, it is very common for just one family member to have them. In addition, they often affect just one part of the body (such as the hands or the feet) without spreading over time to other areas.
There are several types of common warts:
- Plantar Warts are found on the bottom of the foot. They feel deep, but they are still within the superficial layer of the skin.
- Dome-Shaped Warts on the backs of fingers, toes, and knees.
- Periungual Warts are warts around or under the nail.
- Filiform Warts typically appear as a single long stalk (usually on the face.)
- Warts Under the Nails are extremely resistant to treatment. One or two tries by the doctor are worth a shot, but if they fail, putting acid on them yourself just makes them look rough and unattractive.
- “Mosaic” Warts are tiny. So-called “seed warts” can proliferate by the dozens or hundreds all over the sole of the foot. They rarely respond to any sort of treatment, although in this case, too, one or two tries at treatment may be in order. Mosaic warts don’t usually hurt.
