GlossaryKoebner phenomenon

new skin lesions appear on injured skin in certain conditions

The Koebner phenomenon, also known as the Koebner response, is a reaction where new skin lesions appear on previously unaffected skin following trauma or injury in individuals with certain skin conditions, such as psoriasis or vitiligo. This means that if someone with one of these conditions scratches or injures their skin, they might develop new lesions or patches in those areas.
