[Porphyria cutanea tarda in a dialyzed female patient].
Dermatological disorders are a frequent finding in patients with renal insufficiency. Porphyria cutanea tarda, pseudoporphyria, phototoxicity or concurrent bullous diseases may cause the appearance of lesions with liquid content in patients in dialysis. We describe the case of a female patient in dialysis who developed bullous lesions. The clinical and laboratory findings were initially compatible with the suspicion of pseudoporphyria, but the finding of some frankly elevated levels of porphyrins in serum, urine and feces confirmed the diagnosis of porphyria cutanea tarda. Porphyria cutanea tarda and pseudoporphyria present with common clinical manifestations. However, the levels of porphyrins in plasma, urine and feces in pseudoporphyria are normal or slightly elevated.
