A rash. (F.) Exanthame, Elevure. Under this term, is comprehended, by some, every kind of eruption, of which the skin is the seat. Others comprehend by it those eruptions that are accompanied by fever, Febres exanthemattia: including, under the head of the major exanthemata, those which attack a person but once in his life, and which are communicated by specific contagion; and, under the minor exanthemata, those which are not marked by these characteristics. Small-pox, measles, cow-pox, &c., belong to the major :-chicken-pox, herpes, lichen, &c., to the minor. The general acceptation of Exanthem is, however, a more or less vivid, circumscribed, or diffuse redness of the skin, which diminishes, or disappears transiently, under the pressure of the finger.
