Pseudoporphyria is a rare condition of unknown etiology, which manifests as a photo-induced disorder that causes blistering and is distributed in photoexposed areas such as the face, neck, and the dorsal aspect of upper extremities; clinically resembling porphyric diseases, but differs in that it does not cause biochemical alterations and does not raise porphyrin levels in blood, feces and urine. It has been associated with patients requiring hemodialysis and peritoneal dialysis because they present a Uro-D enzyme (urophorfyrinogen descarboxylase) deficit, causing increased oxidative stress at the cellular level.
