Synopsis

Pseudoporphyria is a photodistributed blistering eruption with clinical and histologic features similar to porphyria cutanea tarda (PCT), but there are no porphyrin abnormalities in the plasma, urine, or stool.

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 ultraviolet A (UVA) exposure such as tanning beds, psoralen plus UVA (PUVA) therapy, and excessive natural sun. Pseudoporphyria has also been reported in patients taking over-the-counter chlorophyll-containing supplements. Patients may be reluctant to admit to supplement use unless asked directly about green liquid supplements, green smoothie drinks or green superfoods, or chlorophyll specifically.
