The Köbner phenomenon is by far the best known and the most studied. It is characterized as the appearance of an inflammatory or infectious dermatosis in an area of healthy skin after skin trauma. The dermatoses most frequently concerned are psoriasis, lichen planus and vitiligo. The inverse Köbner phenomenon and the Renbök phenomenon are two very similar phenomena. The first represents the disappearance of a skin lesion after skin trauma. The second is characterized by a skin trauma that is more specifically induced by another dermatosis. Finally, the Wolf’s isotopic phenomenon corresponds to the appearance of a new dermatosis on an area of the skin that was previously the site of another healed dermatosis
