Pseudoporphyria (also known as Pseudoporphyria cutanea tarda) is a bullous photosensitivity that clinically and histologically mimics porphyria cutanea tarda. The difference is that no abnormalities in urine or serum porphyrin is noted on laboratories. Pseudoporphyria has been reported in patients with chronic renal failure treated with hemodialysis and in those with excessive exposure to ultraviolet A (UV-A) by tanning beds.
