Porphyria cutanea tarda occurring in a patient with renal failure, systemic lupus erythematosus and chronic hepatitis C infection treated with hemodialysis.

The diagnosis and management of porphyria cutanea tarda (PCT) is complicated when it occurs in the context of renal failure, chronic hemodialysis, and anemia. We report a case of a woman who presented with painful acral blisters and hyperpigmentation. Her medical history included systemic lupus erythematosus, chronic hepatitis C infection, and renal failure necessitating chronic hemodialysis with a baseline anemia. A highly elevated serum porphyrin level led to the diagnosis of PCT. Treatment with small repeated phlebotomies and concomitant administration of erythropoietin was effective in managing her PCT.
