Porphyria cutanea tarda (PCT) in a patient with chronic renal failure on haemodialysis

Abstract
Porphyria cutanea tarda, diagnosed by reduced levels of red cell uroporphyrin decarboxylase and raised plasma porphyrins, developed in a patient with chronic renal failure due to polycystic kidneys treated on hemodialysis; the patient had normal total urinary and fecal porphyrins. Hemodialysis did not alter plasma porphyrin levels. Most of the plasma porphyrins appeared to be circulating in high MW protein complexes.
