• Pseudoporphyria is a condition clinically and ultrastructurally identical to porphyria cutanea tarda but with no associated abnormality of heme synthesis. A 45-year-old woman with bullae on the dorsa of her hands was found on investigation to have pseudoporphyria. Her symptoms remitted following the cessation of naproxen therapy.
