Correlation of serum and urinary porphyrin levels in porphyria cutanea tarda

Conjunctival squamous cell carcinoma in a patient with hemodialysis‐related porphyria cutanea tarda

“…As a matter of fact, serum porphyrin assays are not routinely available in many laboratories. 6 On the other hand, our patient was confirmed to be infected with HCV in 1993. HCV is a well-known triggering factor among PCT patients, damaging hepatocytes due to microorganism-induced oxidative stress.…”

“…It is known that stool isocoproporphyrin and 24-h urinary excretions of porphyrins are representative of plasma porphyrins, because there is marked variance in urinary porphyrin concentrations in random specimens. 6 In patients with renal failure, a plasma assay may be more reliable than tests of the urine and feces in establishing a diagnosis. 7 Although the amount of urine produced was minimal in our patient, we were able to detect coproporphyrin.…”
