A wart (also known as verruca) is generally a small, rough tumor, typically on hands and feet but often other locations, that can resemble a cauliflower or a solid blister. Warts are common, and are caused by a viral infection, specifically by the human papillomavirus (HPV) and are contagious when in contact with the skin of an infected person. It is also possible to get warts from using towels or other objects. They typically disappear after a few months but can last for years and can recur.
Treatments that may be prescribed by a medical professional include
The wart often regrows after the skin has healed.
One review of 52 clinical trials of various cutaneous wart treatments concluded that topical treatments containing salicylic acid were the best supported, with an average cure rate of 75% observed with salicylic acid compared with 48% for placebo in six placebo-controlled trials including a total of 376 participants. The reviewers also concluded that there was little evidence of a significant benefit of Cryotherapy over placebo or no treatment.
Another over-the-counter product that can aid in wart removal is silver nitrate in the form of a caustic pencil, which is also available at drug stores. This method generally takes three to six daily treatments to be effective. The instructions must be followed to minimize staining of skin and clothing.
The study cited above had 9 patients lost to the follow-up from the original 61 patients entered. In contrast to the flaws (15% of subjects lost to the follow-up) and favorable results of the above study, a more stringent study of 103 children found no benefits from duct tape . The evaluators were blinded during treatment for the most part, a placebo (corn pad) was used and there were no patients lost to the follow-up. After six weeks, rates of wart resolution were similar in the duct tape and corn pad groups and much lower than the rates seen in the earlier trial. A similar trial comparing duct tape with a control treatment with a moleskin pad in 90 adults also found no difference in the rate of wart resolution at the end of two months (21 versus 22 percent) .
