Filiform warts are a proliferative skin lesion that occurs after infection by the human papilloma virus, which produces specially shaped warts. The human body can be infected with the human papilloma virus through direct or indirect contact, which may lead to the development of filiform warts. Filiform warts are elongated, raised warts with a keratinized tip, and are most common on the neck, forehead, eyelids, and underarms. The actual warts can be treated with liquid nitrogen cryotherapy, laser therapy and other physical treatments under the guidance of the doctor, while those who are not suitable for physical treatments can use fluorouracil ointment and other medications. The actual use of medication and treatment should be in accordance with the doctor’s instructions. The actual skin is usually clean, and you need to take good care of it to avoid re-infection.
