Koebner's Phenomenon


Updated January 24, 2010


Occurs when trauma to the skin causes a skin lesion. The amount of trauma required can be very small -- sometimes just rubbing the skin can cause a lesion to develop.

Koebner's phenomenon is seen most often in psoriasis, eczema, lichen planus, and vitiligo.

Pronunciation: KOHB-ner
