Changes of the nails include onycholysis, pitting, thickening, oil spots and crumbling. At some point, as many as one third of patients may develop a Köbner phenomenon, which is a condition in which new insult or skin trauma is greeted with a development of psoriatic lesions. Greater risk of postsurgical infections also is found, due to a higher-than-normal bacterial colonization of the skin and psoriatic lesions.
