Study design summary
Molluscum contagiosum (MC) is a skin condition that commonly affects children and can result in discomfort, pain, and in some cases emotional and psychological distress. This study aims to develop and test a tool to help a child’s parent diagnose MC, and to describe the presentation, burden, management and natural history of MC in the community.

The study involves three stages. Firstly, we will develop a tool, ‘McTool’, through use of clinical photography, consultation with dermatologists and piloting in a dermatology clinic. This tool will help parent’s diagnose if their child has MC. In the next stage, we will test the diagnostic value of this tool by comparing diagnosis made by parents with that made by their general practitioner. In the final stage, we will use this tool to help recruit a group of patients with MC for an observational study that will involve collecting baseline data (Diagnosis and Quality of Life) and following them over time to record management and resolution of symptoms.

This study will form part of a PhD thesis exploring the impacts of molluscum contagiosum in children aged 1 to 14 in the UK. Information relating to numbers effected, length of lesions and impact upon quality of life will be of immediate use to parents, primary care clinicians, and researchers, it will also establish a tool for identifying patients with Molluscum Contagiosum by non-clinicians, which will be useful for clinical and research uses.
