What does the term 'urticaria' refer to?

Explanation:
The term 'urticaria' specifically refers to hives, which are characterized by raised, itchy welts on the skin. It is a common condition resulting from an allergic reaction or other triggers that cause the release of histamine and other chemicals from mast cells in the skin. This release results in localized swelling and redness, manifesting as itchy, raised areas known as wheals. Understanding the nature of urticaria is essential because it can be acute or chronic and may have various underlying causes including allergens, medications, or even stress. In contrast, skin cancer, fungal infections, and autoimmune disorders involve different pathophysiological processes and clinical presentations, thus making them distinct from the specific characteristics of urticaria.
