[Porphyria cutanea tarda-like bullous dermatosis in a patient with chronic renal failure under hemodialysis].

Patients with chronic renal failure under regular hemodialysis may present porphyria cutanea tarda-like dermatoses without, however, exhibiting a disturbed porphyrin metabolism. Based on a personal observation and the literature the anamnestic, clinical and histological features of this distinct dermatosis are discussed. Metabolic disturbances due to chronic renal failure, with or without hemodialysis, are possible etiopathogenetic factors, while in the light of the latest findings it seems improbable that any such role is played by frusemide therapy.
