Common warts, commonly known as wart, are benign growths that occur when the body is infected with the human papillomavirus, a viral skin disease. Most warts are caused by infection with HPV-2, which increases the risk of developing warts when the body’s skin is broken or exposed to moisture for long periods of time. Usually, common warts occur in children, adolescents, or those who are immunocompromised. They are usually flat, grayish-white papules with a pin-cap size and a rough surface. They may appear cauliflower-like or papillomatous, hard to the touch, and may be solitary or multiple, or may fuse together to form plaques. There are usually no conscious symptoms, but there may be occasional pressure pain, especially if the affected area is rubbed repeatedly. If a patient develops these symptoms, he or she needs to visit a hospital dermatologist. The patient will be given a physical examination and HPV-DNA test to determine if he or she has common warts under the guidance of a professional doctor. The process of common warts is slow and self-limiting. Some patients’ warts can subside on their own within 3 years, so don’t worry too much. If you’re looking for a good deal of skin, you can use medication to remove it, such as salicylic acid and retinoic acid, to remove the warts by damaging them, or you can use physical therapy to remove them, such as laser, freezing, electric drying and electrocautery. In addition, surgery can also remove the warts. In daily life, good habits should be practiced to promote recovery. If physical or surgical treatment is performed, you need to keep the wound dry and avoid scratching to avoid secondary infection.
