ACHENBACH, R E. The Koebner phenomenon. Rev. argent. dermatol. [online]. 2011, vol.92, n.3. ISSN 1851-300X.

First described in 1871, the Koebner phenomenon is one of the most well-known entities in dermatology. Heinrich Koebner is credited with the first adequate description of this peculiar disposition of psoriatic skin. He was one of the outstanding dermatologists of the 19^th Century and reported the formation of psoriasiform lesions in uninvolved skin after excoriations and horse bites. Types of Koebner response, a list of injuries capable to produce it and a review of the pathogenesis are reviewed.
