Acquired perforating dermatoses are usually also highly pruritic. Calciphylaxis is asevere disease with poor prognosis. Nonhealing wounds with superinfection and progression to sepsis are characteristic. Bullous lesions can be caused by disturbances in porphyrin metabolism. Nephrogenic systemic fibrosis is adisease which was first described in 2000. Its incidence is already on the decline. Furthermore, this article provides an overview of systemic diseases which have both skin symptoms and kidney changes. These include connective tissue diseases, vasculitis or sarcoidosis and amyloidosis. After akidney transplantation, particular attention must be paid to the development of skin tumors and infections. The last part of this article is dedicated to genodermatoses with skin and renal involvement, where numerous causative mutations have already been characterized.
