Treatment of porphyria cutanea tarda with phlebotomy in a patient on peritoneal dialysis.

Porphyria cutanea tarda (PCT) is frequently described among patients with chronic renal failure undergoing hemodialysis. One patient who was receiving peritoneal dialysis and had PCT develop has been described in the literature. However, it was later determined that the patient's PCT was related to the hepatotoxic drug she was receiving rather than her peritoneal dialysis. Our patient is the first reported case, to our knowledge, of a patient with end-stage renal disease with negative hepatitis serology who was not receiving a hepatotoxic drug, or on hemodialysis, who had PCT develop while receiving peritoneal dialysis.
