This condition consists of a wheal and flare reaction with associated pruritus. The wheal is a papule or plaque that is smooth. The flare is a pink to red color in lighter skin tones and becomes more hyperpigmented as the skin tone deepens in color. Lesions typically last less than 24 hours with no residual pigmentation. Note that If the lesion lasts greater than that and/or heals with hyperpigmentation, urticarial vasculitis should be considered.
