Abstract

Neurophilic urticarial dermatosis (NUD) is a new, important differential diagnosis of urticarial rashes. It is a clinical and histological response pattern that strongly correlates with systemic disease. Both autoinflammatory and autoimmune conditions can be present in patients with NUD. In this article the clinical and histological criteria of NUD, diagnostic considerations and the diseases most frequently associated with NUD are discussed.
