A 65-year-old man presents with a three-day history of a rash on his feet. He had just completed a course of trimethoprim for an attack of prostatitis. He woke up with the feet reddened and hot and both feet seemed equally involved. Over the next two days his rash persisted and there was blistering on both sides. An illustration of his feet is shown. The line markings were made the previous day. He has a history of chronic arthritis of his knees and back, for which he takes regular paracetamol. He remembers having a rash with the same distribution after being treated for a urinary tract infection some years ago. Which one of the following is the most likely diagnosis?

(E) Systemic lupus erythematosus
