Urticaria is an example of which type of skin lesion?

  1. Secondary Lesion

  2. Primary Lesion

  3. Vesicular Lesion

  4. Crust

The correct answer is: Primary Lesion

Urticaria, commonly known as hives, is classified as a primary lesion. Primary lesions are the initial morphological changes in the skin that are directly associated with a disease process. They appear as the first signs of skin conditions, such as macules, papules, and wheals, which are characteristic of urticaria. Wheals, which are raised, itchy areas, often develop due to allergic reactions or other triggers, making them a distinct primary lesion. In contrast, secondary lesions arise from changes to primary lesions or result from the progression or alteration of the skin's appearance due to external factors, such as scratching or infection. Since urticaria specifically manifests as an immediate reaction and forms part of the initial skin presentation, it falls appropriately under the category of primary lesions.
