Koebner phenomenon
[edit]Koebner was a renowned dermatologist known for his research of psoriasis, epidermolysis bullosa simplex and various fungal disorders. He is best known for the eponymous "Koebner phenomenon", also known as isomorphic phenomenon. The Koebner phenomenon is the development of isomorphicpathologiclesions in the traumatized "uninvolved skin" of persons who have cutaneous diseases such as psoriasis. In other words, if a person has psoriasis, an injury is followed by new psoriatic lesions on the injured but otherwise normal (formerly non-psoriatic) skin, and these new lesions are similar to those of the diseased (originally psoriatic) skin in a clinical and histopatho

Koebner phenomenon
Appearance of skin lesions on lines of trauma
The Koebner phenomenon or Köbner phenomenon (, ),[1] also called the Koebner response or the isomorphic response, attributed to Heinrich Köbner, is the appearance of skin lesions on lines of trauma.[2] The Koebner phenomenon may result from either a linear exposure or irritation. Conditions demonstrating linear lesions after a linear exposure to a causative agent include: molluscum contagiosum, warts and toxicodendron dermatitis (a dermatitis caused by a genus of plants including poison ivy). Warts and molluscum contagiosum lesions can be spread in linear patterns by self-scratching ("auto-inoculation"). Toxicodendron dermatitis lesions are often linear from brushing up against the plant. Causes of the Koebner phenomenon that are secondary to scratching rather than an infective or chemical cause include vitiligo, psoriasis, lichen planus, lichen nitidus, pityriasis rubra pilaris, and keratosis follicularis (Darier disease).[citation needed]
