[Dermatosis bullosa in patient with chronic renal failure under hemodialysis treatment--case report].

A case of 45-year-old patient with chronic renal failure treated by hemodialysis associated with skin changes typical for porphyria cutanea tarda is reported. The diagnosis was based on clinical manifestations and on histopathologic examination of the skin segment. The skin was low sensitive for UVA rays, serum levels of aluminium and lead were significantly elevated. We did not find porphyrins in the urine (24-hour collection 100 ml) as well as in the dialysis fluid.
