Dermal micro-angiopathy in patients with analgesic nephropathy

Skin biopsy specimens of 10 patients suffering from analgesic nephropathy revealed a micro-angiopathy similar to that seen in the kidney and urinary tract of patients with this disease. It is considered to be part of a disseminated micro-angiopathy. Similar changes were not observed in normal controls or in patients suffering from chronic renal disease due to other causes.
