In this comprehensive exploration, we delve into the intricate pathophysiology of Prurigo Nodularis (PN), highlighting the pivotal roles of neuronal sensitization, inflammation, and pruritus. This challenging dermatological condition is characterized by dermatological condition histopathologic alterations, including enhanced hypervascularization, epidermal hyperkeratosis, and dermal fibrosis. Explore the connection between PN and the proinflammatory Th2 cytokine IL-13, shedding light on its binding to IL-4R across various skin components.
