Sunbed-induced pseudoporphyria

Abstract
The Clinical details of four fair‐skinned women with recurrent blistering and skin fragility are presented. All had considerable sun‐exposure and had used sunbeds for years. Specific causes of bullous dermatoses including drug ingestion, porphyria, cutaneous amyloidosis and epidermolysis bullosa acquisita were excluded. Long‐term recurrent exposure to high doses of sunbed radiation in chronically sun‐damaged skin appears to be a further cause of pseudoporphyria.
