Chronic idiopathic urticaria

Chronic idiopathic urticaria, also referred to as chronic spontaneous urticaria, is an inflammatory dermatologic condition characterized by the recurrent appearance of pruritic wheals, angioedema, or both for six weeks or longer without an identifiable external trigger or allergic cause Pathophysiologically, it is driven by the activation and degranulation of skin mast cells and basophils, which release histamine, leukotrienes, and other proinflammatory mediators
