IMPETIGO

(Lat.), n. f. Iam-pest-i(e)'RO. Gen., -ig'in is. From impetere, to attack. Gr., \tixyv. Fr., impetigo, dartre humide, melitagro, gourme. Ger., Krustenflechte, feuchter (oder nci ender) Grind. it.,impetigine,impetigyine. 1. A dermatological term employed by different writers and at different periods with varying significations. Of the four varieties of the disease described under this name by Celsus, the first, characterized by pimples (var i), pustules, vesicles, and scales, may have included, besides eczema, i. in the " modern sense of the term (v. infra); the second, or red," variety was probably eczema; the third, or " black," variety, which was "thicker, harder, and more swollen," "produces fi ures and corrodes violently,"and was attended with the production of a spreading black scale or crust, may have been either impetiginous eczema or a gangrenous affection; the fourth variety, " not curable" and characterized by white scales the removal of which sometimes caused blood to appear, was probably psoriasis. 2. Peter Frank designated as " impetigines " (pi. of t.)all chronic forms of skin disease, the acute forms being termed " exanthemata." 3. Scho'nlein limited the term "impetigines" to those forms of skin disease that were superficial in character, corresponding nearly to the " eczema toses " of Fuchs. 4. Plenck employed the term for a red, dry, itching eruption that tended to become general over the whole body, and terminated with the formation of "furfures," or " light scales." 5. In its modern sense, as first defined by Will an, the term signifies a disease of the skin characterized by an eruption of small, yellow, itching pustules, occurring often in groups, and ending with the production of thin, scaly, yellowish crusts. By Hebra, and by many recent writers the term has been discarded as implying a disease sui generis, the eruption being regarded simply as a form of pustulation incident to eczema.
