The Koebner phenomenon (isomorphic response) is defined as the development of 
typical lesions of a dermatosis that occur in areas of trauma in previously 
uninvolved skin. Rare reports have suggested that striae are a form of injury to 
the skin that can result in koebnerization of psoriasis, vitiligo, and lichen 
planus. We herein report a 27-year-old female patient with plaque psoriasis who 
developed psoriatic lesions along striae distensae.
