The History of Dermatology

"The Skin is obnoxious to many troublesome Disaffections, which disguise the face, and whole surface of the Body, among which the Itch, and Scab, and so many vexatious Diseases, may justly claim our notice, that we may inquire into their Nature; which maketh way for a cure, most acceptable to  Patients, who are much desirous to quit  such importunate Guests, giving frequent disposures, ingrate Eye-sores and nasty itchings, attended sometime with a dry Skurf, and Scab, and other times, with divers moist wheals, tipped with white Heads, as so many minute Ulcers, determining in Scabs upon Frication, speaking a high delight, to countermand the afflictive solicitations, of burning Itchings."  - Samuel Collins, A Systeme Of Anatomy, Treating Of the Body of Man, Beasts, Birds, Fish, Insects, and Plants: ... And After Every Part of Man's Body Hath Been Anatomically Described, Its Diseases, Cases, and Cures are Concisely Exhibited,  1685.
