Filiform warts are caused by infection with human papillomavirus and are transmitted. People with low immunity and broken skin are susceptible to this virus.
Filiform warts are a benign proliferative disease caused by human papillomavirus infection of the skin and mucous membranes. The main symptom is the appearance of a single filiform protuberance in the affected area, mostly brown, rough surface, and patients often do not have self-conscious symptoms. Usually, people with low immunity or traumatized skin are more likely to be infected with the virus.
After the disease, some patients’ symptoms disappear over time. If symptoms persist, topical medications such as salicylic acid and retinoic acid may also be considered. Treatment can also be combined with surgery and physical therapy such as laser, electrocautery, and liquid nitrogen freezing.
If medical intervention is required, it is important to follow medical advice.
