Fixed drug eruption from sodium benzoate.
We report a fixed drug eruption caused by a syrup containing sodium benzoate. Our patient gave a positive reaction to a patch test and to a provocation test after 15 h ingestion, but no patch test reaction in the interdigital area where the patient had previous lesions.
