What term defines an itchy, swollen lesion typically caused by insect bites or skin allergies?

1. Hive

2. Ulcer

3. Scale

4. Keloid

The correct answer is: Hive

The term that defines an itchy, swollen lesion typically caused by insect bites or skin allergies is "hive." Hives, also known as urticaria, are raised, red, or skin-colored welts that can vary in size and are often associated with an allergic reaction to substances like insect venom, food, or medication. They are characterized by their ability to itch and their transient nature, often appearing and disappearing rapidly. In contrast, ulcers refer to open sores on the skin or mucous membranes that result from loss of tissue, typically involving deeper layers of the skin and are not defined by itchiness or swelling from allergens. Scales are dry, flaky patches of skin resulting from conditions such as psoriasis or eczema, rather than acute allergic responses. Keloids are raised scars that form due to excessive collagen production during the healing process, and they do not present as itchy, swollen lesions in response to irritants like hives do. Understanding these distinctions helps clarify why "hive" is the correct answer for this description.
