Wheal is also known as:

• A. Vesicle
• B. Urticaria
• C. Macule

Because wheals are the defining lesions of urticaria, this term is most accurately described as urticaria. In contrast, a vesicle is a small fluid-filled blister, a macule is a flat discolored patch with no elevation, and an ulcer is a break in the skin with tissue loss.
