What is the Koebner phenomenon associated with?

The Koebner phenomenon is primarily associated with skin trauma leading to the development of new psoriatic plaques. This phenomenon occurs when individuals with psoriasis develop lesions in response to skin injuries or trauma, such as cuts, scrapes, or sunburns. Essentially, the skin reacts to damage by exhibiting the characteristic lesions of psoriasis at the site of injury, which indicates a pathological response that reflects the underlying autoimmune nature of the disease.

Understanding this concept is crucial for managing psoriasis and informing patients about triggers that may worsen their condition. While options related to the development of psoriasis over healthy skin and retention of body heat may touch on related topics, they do not capture the specific mechanism of the Koebner phenomenon as accurately as the correct answer does. Wound healing disturbances are also relevant to skin conditions but do not specifically encompass the unique response seen in psoriasis related to trauma. This clear association between trauma and psoriatic plaque formation is what defines the Koebner phenomenon in clinical practice.
