Porfiria cutánea tarda en dos pacientes con trasplante renal / Cutanea tarda porphyria in 2 patients with kidney transplantation

Two patients who developed porphyria cutanea tarda, six and eight years after a successful renal transplantation are reported. There was no history, in either of them, of alcohol abuse, blood transfusion, iron or estrogen therapy and any hemodialysis in the last years. There is no evidence to support that a renal allograft is capable to develop porphyria cutanea tarda. Nevertheless, it would be interesting to consider its possible influence, due to the longer survival of these patients.
