Study of a Cohort of Children With Molluscum Contagiosum (MC) Treated With a 5% Solution of Potassium Hydroxide (Molutrex®) Applied Locally to the Skin

Molutrex® a 5% potassium hydroxide solution for topical application to the skin. Molutrex® is intended for the superficial treatment of certain types of warts, molluscum contagiosum and is composed of potassium hydroxide (5%) purified water. With regard to the 2017/745 RDM, he is a class IIa medical device. In accordance with Regulation (EU) 2017/745 of the European Parliament and of the Council of April 5, 2017 relating to medical devices, as part of the Molutrex® Post-Marketing Monitoring Plan, the objective of this study is to have data on the performance , safety and suitability for real-life use of Molutrex® in a prospective cohort of patients with molluscum contagiosum.Since molluscum contagiosum is most prevalent in children, and potassium hydroxide is used very little in adults (because most often they are immunocompromised patients requiring other antiviral treatments), the study will be conducted in children aged 2 to 10 years. This population represents the majority of patients treated with Molutrex®, although the product can be used in adults. The study includes 2 visits, the objective of the study being to evaluate the percentage of children healed at 45 days, healing defined by a reduction of more than 90% in the number of lesions present at inclusion in the study.
