Li replied to Wang Zhao's patient in Yingcheng, Hubei-how to treat verruca plana?
Verruca plana is a common skin disease caused by human papillomavirus (HPV). It occurs in teenagers, so it is also called verruca plana. Folk call it "flat monkey". It mainly occurs on the back of the hand and face, showing flat papules as big as rice grains and beans. Most patients are scattered and multiple, and can also be combined into pieces or arranged in strips along hand scratches (isomorphic reaction), showing light brown or normal skin color. Recently, using nucleic acid hybridization technology, it has been confirmed that there are more than 100 antigenic types of human papillomavirus, among which 3, 10, 28 and 4 1 types cause verruca plana, etc. Infection is caused by skin trauma, sometimes careless abrasion. It is generally believed that the low specific immunity to human papillomavirus (low cellular immune function) is an important factor affecting its onset and course of disease. Pingpang generally has no conscious symptoms or slight itching, and the course of disease is chronic, which affects the appearance, so people are eager to seek treatment after illness. In the past, Banlangen, inositol, dipyridamole, levamisole, herpetin, phthalamide and other drugs were generally used, and a few patients were treated with laser, freezing and electrocautery. In recent years, interferon, transfer factor, cimetidine and other drugs to improve the body's immunity have been widely used, and wart implantation has been used to treat verruca plana. There are many treatments, all of which have certain effects. Unfortunately, all methods are not specific drugs, and each patient's methods are different.
