Plaque

Front 34

a special type of papule or plaque which is the response of the skin to histamine release and is characterized by the classic three features (triple response of Lewis) of edema, erythema, and a flare. The edema fluid is bound, which contrasts this lesion with the vesicle and bulla. transitory or evanescent, seldom remaining in one location for more than 3 or 4 hours.
