Cephalosporin‐induced linear IgA dermatosis in a child: Case report and literature review

Linear IgA dermatosis (LAD) is a rare, subepidermal blistering disease with mucocutaneous involvement. It may be idiopathic or drug induced. We describe a 4‐year‐old girl who presented with a vesiculobullous eruption after she had been treated with cefixime for urinary tract infection. A diagnosis of drug‐induced LAD was made based on clinical, histopathological, and immunofluorescence findings. Naranjo adverse drug reaction algorithm was used to assess imputability resulting with a “probable” association. In literature, cephalosporin antibiotics are rarely reported in association with LAD. To our knowledge, this is the first case of a cefixime‐induced LAD among adults and children.
