Introduction Welcome to our blog! Today, we explore an important topic that affects many but is often misunderstood: Vulvar Lichen Sclerosus (VLS). This chronic inflammatory skin condition primarily affects the vulvar region and has long been known to be rare. However, recent studies and a European scoping review reveal new insights into its prevalence, burden, and challenges. This post examines how common VLS is and why it qualifies as a high-burden condition despite lacking adequate funding and research. We discuss the criteria for classifying a disease as "rare." Finally, we share personal insights from individuals with firsthand experience with VLS. Let's dive in!
