Synopsis

Pseudoporphyria is a photodistributed blistering eruption that has the histologic features of porphyria cutanea tarda (PCT). Absent are the abnormalities in porphyrin metabolism seen in PCT.

While commonly associated with NSAIDs, antibiotics, and diuretics with sulfa moieties, pseudoporphyria can also be seen in chronic renal failure (with or without hemodialysis) and with UVA exposure such as tanning beds, PUVA, and excessive natural sun.
