Moxifloxacin as the likely cause of drug-induced linear immunoglobulin A bullous dermatosis.

Linear immunoglobulin A bullous dermatosis (LABD) is an immune-mediated subepidermal blistering disease that can be triggered by drug exposures, most notably, vancomycin. The authors report of a case of a 72-year-old man who developed LABD after a course of moxifloxacin. To the authors' knowledge, there is no other case of LABD caused by moxifloxacin in the medical literature.
