Common warts and flat warts are caused by infections of the same virus, mainly due to Human Papillomavirus (HPV), but not by the same type. There are over one hundred types of HPV, with more than eighty types associated with human diseases. The types of HPV that cause flat warts are mainly type 3 and type 5, while the types that cause common warts are mainly HPV type 1, type 2, type 4, and type 7. Therefore, common warts and flat warts are caused by different types of HPV infections. The appearance of flat warts and common warts is primarily due to minor lesions in the skin and mucous membranes, allowing the virus to enter the epithelial cells of the human body. There, the virus replicates and proliferates, leading to abnormal proliferation and differentiation of epithelial cells, forming benign growths on the epidermis.

Are common warts and plantar warts the same?

Plantar warts are common warts that occur on the soles of the feet. Therefore, plantar warts are a special type of common wart that occurs on the soles of the feet. Plantar warts belong to the category of common warts. Common warts are caused by the human papillomavirus (HPV), which infects the skin and mucous membranes, resulting in benign growths such as common warts, flat warts, or genital warts, among others. However, the subtypes of HPV causing these infections vary. Additionally, within common warts, those occurring on the soles of the feet are specifically referred to as plantar warts. Plantar warts mainly appear on the front part of the sole, which is an area subject to friction and often sweatier, thus making it more susceptible to warts. These warts can be painful, or they might not cause any discomfort at all.

Will common warts grow back after being removed?

Common warts, even when picked off, are very likely to regrow, as they are benign growths caused by an infection of the skin and mucous membrane with the Human Papillomavirus, or HPV. Due to their viral nature, they tend to recur easily. Common warts, also known as verruca vulgaris or plantar warts, are typically caused by HPV type 2 and mainly occur between the ages of 5 and 20. They can appear on any part of the body due to autoinoculation and are most commonly found on the hands and feet. These areas are susceptible due to frequent injuries or prolonged exposure to water, which are common triggering factors. After a wart is removed, the surrounding areas might already be infected, potentially leading to new warts appearing over time.

What should I do if new warts grow around the area after freezing common warts?

After cryotherapy for common warts, it is common for new warts to appear around the treated area. This is because common warts are caused by an infection with the human papillomavirus (HPV), a type of viral skin disease that tends to recur. Persistence in treatment is necessary in such cases. Treatments such as liquid nitrogen cryotherapy, carbon dioxide laser therapy, or high-frequency electronic ion cautery can be used. The occurrence of common warts is usually related to decreased immune function in the body. Therefore, it might be beneficial to use immunomodulators, such as interferon or thymopeptides enteric capsules, which have certain inhibitory effects. Concurrently, some traditional Chinese medicines that clear heat and detoxify, soothe the wind and balance the liver, along with other topical Chinese herbal treatments, can be used. A combined approach of Chinese and Western medicine often results in better outcomes. It is also important to engage in appropriate exercise to boost the body's immune system.
