What department should I visit at the hospital for filiform warts?

Filiform warts typically require a visit to the dermatology department of a hospital.

Filiform warts are primarily caused by human papillomavirus (HPV) infection and commonly occur on the neck, eyelids, and other areas. They manifest as fine, soft, thread-like projections on the skin surface, usually brownish-gray or matching normal skin color. Most cases are asymptomatic; however, in rare instances, they may trigger keratitis or conjunctivitis. As a cutaneous condition, filiform warts should be diagnosed at a hospital dermatology department via histopathological examination and HPV DNA testing. Treatment—under physician guidance—may include laser ablation or cryotherapy.

Filiform warts are mildly contagious. During treatment, maintain good skin hygiene and avoid scratching or touching affected areas to prevent local skin damage, cosmetic changes, pain, or proliferation of lesions. In daily life, adopt a light, bland diet; minimize direct sun exposure; and reduce contact with polluted environments.
