It is characterized by intensely pruritic, firm nodules, typically 1-2 cm in diameter, which usually develop on the extensor surfaces of the extremities. Histopathologically, the following characteristics are observed in PN lesions: (1) dermal cellular infiltrates composed of type 2 inflammation-associated immune cells with lesional overexpression of type 2 cytokines (including IL-4, IL-13, and IL-31); (2) dermal fibrosis; and (3) epidermal hyperplasia with hyperkeratosis. Additionally, functional and structural alterations of cutaneous sensory nerve fibers profoundly contribute to itch in cooperation with type 2 inflammation. This abnormal interaction is referred to as neuroimmune dysregulation. The scratching behavior induced by itching from neuroimmune dysregulation initiates the development of prurigo nodules. This distinctive pathogenic feature of \"itch-first\" in PN is distinct from \"inflammation-first\" in atopic dermatitis, another pruritic skin disease with type 2 inflammation. In atopic dermatitis, the skin initially exhibits type 2 inflammation, which is subsequently followed by itching.

We focus on the relationship between PN and APD in CKD and provide data to support that both entities share many of the same clinical and histologic features. These cutaneous diseases often go underreported in this patient population, leading to inadequate treatment and suboptimal patient outcomes. Our review of the literature suggests a relationship between PN/APD and CKD, presumably driven by uremic pruritus, changes in the renin-angiotensin-aldosterone system, a predisposing immune dysregulation with increased IL-31 expression, and opioid system imbalances.
