Dermatology - Wheals
Wheals occur as a result of edema in the papillary layer of the dermis. An eruption characterized by raised, itchy skin lesions is referred to as an urticarial exanthema or urticaria.
A wheal is a transient skin lesion that appears as a pale red papule or plaque with a rounded or flat top, and often disappears within 24-48 hours.
The wheals might have a circular, swirling, or irregular appearance, with fast changing pseudopods that vary in size and shape due to the shifting swelling of the skin's papillary layer.
Wheals can be detected through palpation.
