Lichen Simplex Agrius by Bateman Thomas (1 results)

Delineations of Cutaneous Diseases, 4. - London, Henry G. Bohn, 1815 (1849), 1 hand colored engraved plate, 246 x 242 mm, added a descriptive text leaf. Comprises two species of LICHEN, a non-contagious, papular eruption, affecting adults. Fig. 1.-The LICHEN simplex; which is characterized by a scat tered eruption of distinct red papula, with a very moderate inflammation surrounding their base, terminating with a slight scurfy exfoliation of the cuticle. It is liable to be mistaken for the itch, the eruption of which, however, is usually less red, and more humid, being vesicular or postular, but seldom purely papular. The distinct and distant papulae distinguish it from the measles and scarlatina, for which it has been mistaken. Fig. 2.-The LICHEN agrius; which is a more inflammatory form of the disease, and marked by the highly red hue of some of its patches, the skin of which becomes at length harsh, thickened, chapped, and excoriated. This tendency, and the diffuse redness, connecting the papules, distinguish this Lichen from the other species. "In 1814 Bateman acquired the copyright to the engravings in the Willan treatise. He arranged to have the plates refurbished,".
