A 46-year-old man attends the ED with an itchy rash on both his forearms. It started yesterday evening, and has worsened today. He spent yesterday weeding his garden in the sunshine, wearing gloves and a short-sleeved t-shirt. He has no prior history of skin disease or any comorbidity and is taking no medications.

On examination there are erythematous linear patches, weals and developing blisters over both forearms (shown). The remainder of his skin is unaffected.
