Filiform warts generally do not itch and are caused by an infection with the human papillomavirus (HPV), which has a certain degree of contagiousness. Filiform warts typically appear in areas such as the neck, armpits, and groin. They do not impact health but can affect appearance. Filiform warts are a special type of common wart. In clinical treatment, the main methods include using carbon dioxide laser treatment or cryotherapy with liquid nitrogen. The occurrence of filiform warts is somewhat related to a decrease in body immunity. If one finds cryotherapy or carbon dioxide laser treatment painful, topical ointments can be an option. Interferon ointments, for instance, can be helpful.
