Successful clearance of facial common warts by local hyperthermia: report of two cases.

Facial common wart is a disfiguring condition caused by human papilloma virus infection. Choices to treat facial warts should be cautious, in consideration of adverse cosmetic consequences. Two cases of facial common warts were treated by local hyperthermia at 44 °C for 30 minutes, once a day for three consecutive days (the first session), and similarly treated a week later for more 2 days (second session). The warts completely disappeared in 10 and 12 weeks, respectively in the two patients. Adverse effect was tolerable burning sensation in the two patients and a temporary heat-induced blistering in one of them. This pioneer trial suggested that mild hyperthermia is a safe and effective method in treating facial common warts.
