title: Adverse cutaneous reaction to naproxen: a missed diagnosis fortuitously resolved.
abstract: A 91-year-old man presented with a one-month history of swollen legs and dyspnoea. He also complained of a 16-year chronic rash that had caused him considerable morbidity and cosmetic problems. He had been taking naproxen for several years for osteoarthritis. Clinical examination demonstrated bilateral pitting oedema of the leg and a widespread excoriated rash that affected most of his body. A clinical diagnosis of fluid retention secondary to naproxen was made. Stopping naproxen led not only to the resolution of his leg oedema and dyspnoea, but also to the prompt and complete remission of the rash. Reviewing the patient's history revealed that the rash had almost certainly first appeared when naproxen was started many years previously.
