A Case of Photosensitive Drug Eruption Induced by Sitafloxacin

Abstract

　A 79-year-old man was treated with ethambutol and clarithromycin for non-tuberculous mycobacteriosis and later started taking sitafloxacin because of exacerbation of his respiratory condition. One month later, he developed erythema on the face, neck and dorsal aspects of both hands the day after working in strong sunlight. Sitafloxacin showed a positive reaction in a photo-drug test with UVA irradiation dose of less than 1.5 J/cm². A diagnosis of photosensitive drug eruption induced by sitafloxacin was made.
