[Fenofibrate photoallergy].

Photosensitization to lipid-lowering fibric acid derivatives are rare. We report a case of photoallergy induced by fenofibrate, proved by a positive UVA photo-patch-test. Evolution towards persistent photosensitization is probable, since photobiological abnormalities persisted during four months after fenofibrate was discontinued. The fact that patch-tests to various benzophenones were negative is not in favour of the benzophenone group being responsible for the photosensitization reaction.
