Filiform warts are a type of skin disease caused by the human papillomavirus infection, and they belong to a kind of common warts, often seen in women, with a certain degree of contagiosity. They are usually related to a decline in the body’s immune function. For example, in cancer patients or those with HIV where the immune system is compromised, filiform warts can easily occur.

The clinical presentation of filiform warts typically includes brown or light brown lesions, some of which match the normal skin tone. They appear as elongated, soft, pedunculated growths and can vary in number from several to several hundred. They generally occur on eyelids, neck, and scalp among other areas. For the treatment of filiform warts, options under medical guidance include using carbon dioxide laser therapy, cryotherapy with liquid nitrogen, or removal through high-frequency electrical ion cauterization.
