Filiform warts, also known as skin tags, often have a certain family history and are common among overweight adults, particularly around the neck area. It is important to enhance skin cleanliness. Partially, the cause is a viral infection by the Human Papillomavirus, abbreviated as HPV.

When necessary, physical treatments such as cryotherapy with liquid nitrogen or laser removal commonly used in clinical settings can be adopted to remove the warts. These methods are complemented by immune modulation, such as taking oral thymopentin enteric capsules, and applying interferon gel on the affected skin area to inhibit viral replication. The contagiousness is not very strong. It is advised to disinfect underwear and avoid harmful stimuli such as scratching or squeezing.
