Fixed Drug Eruption due to Ciprofloxacin / 대한피부과학회지

ABSTRACT

Fixed drug eruption is a pattern of a drug-induced cutaneous reaction. It is characterized by skin erythematous plaques that recur at the same site each time the drug is administered. Now, we report the case of a 26-year-old woman who presented with 2 ill-defined erythematous patches on her back with itching sensation. The patient had a history of ciprofloxacin medication. The patch test with suspected drugs showed negative reactions, but intradermal tests were positive reactions. The patient was diagnosed with fixed-drug eruption due to ciprofloxacin.
