Molluscum contagiosum and filiform warts can be distinguished from each other in terms of etiology, clinical manifestations and treatment methods. 1. Etiology: molluscum contagiosum is mainly related to repeated friction or local dampness and irritation. It causes the formation of abnormal proliferation of local skin tissues. Filiform warts are mainly contact infections caused by human papillomavirus infection of the skin or mucous membranes. 2. Clinical manifestations: Molluscum contagiosum is mainly a soft proliferation of the skin protruding outward. They are generally small in number and are not contagious. Filiform warts are mainly filamentous or spiny projections, soft to the touch, and can be pulled out with a little force, and cause local bleeding, and are somewhat infectious. 3. Treatment: Molluscum contagiosum is usually removed by freezing or laser, and can usually be cured. Filiform warts can be treated with medications such as salicylic acid and retinoic acid, in addition to laser or liquid nitrogen freezing. If the patient is suspected of molluscum contagiosum or filiform warts, it is recommended to consult a doctor in a timely manner, follow the doctor’s instructions for further examination, with the help of the doctor to clarify the cause, and targeted treatment or treatment.
