Koebner phenomenon
Koebner Phenomenon
Koebner Phenomenon (pronounced: kœb-nər fəˈnäməˌnän) is a medical condition named after the German dermatologist Heinrich Koebner, who first described it in the 19th century.
Etymology
The term "Koebner Phenomenon" is derived from the name of its discoverer, Heinrich Koebner. The term "phenomenon" is derived from the Greek word "phainomenon", which means "that which appears" or "experience".
Definition
The Koebner Phenomenon, also known as the Koebner Response or Isomorphic Response, refers to the appearance of skin lesions on areas of the body that have been physically injured or traumatized. These lesions are identical to those present in the original disease that affects the patient.

Clinical Significance
The Koebner Phenomenon is most commonly associated with psoriasis, but it can also occur in other skin diseases such as vitiligo, lichen planus, and pityriasis rubra pilaris. It is important for patients with these conditions to avoid skin trauma as much as possible to prevent the occurrence of the Koebner Phenomenon.
