Érythème pigmenté fixe à la clarithromycine : importance des tests de provocation pour le diagnostic

FDEs to macrolides are rare, and herein we report a new case. Our observation confirms the diagnostic value of challenge tests in FDE. These tests should only be performed in the event of non-severe FDE, in other words not in bullous or systemic reactions, and they often constitute the only diagnostic approach possible, since skin tests are rarely positive during investigation for FDE.
