ABSTRACT
Linear IgA bullous dermatosis (LABD) is a rare autoimmune subepidermal bullous disease characterized by a linear pattern of IgA deposition along the basement membrane zone. The etiology of LABD is unknown but a minority of cases are drug-induced. Although vancomycin is the agent most commonly implicated in the pathogenesis of drug-induced LABD, association with other agents including phenytoin, piroxicam, captopril, diclofenac sodium and cyclosporine have also been reported. We describe a case of linear IgA bullous dermatosis which probably developed after captopril treatment in a 51-year-old male patient with infective endocarditis.

Linear IgA bullous dermatosis (LABD) is an uncommon acquired autoimmune subepidermal bullous disease characterized by the linear deposition of IgA at the basement membrane zone. Although LABD is most often idiopathic, drug-induced LABD may, occur in rare occasions. We report a case of vancomycin-induced LABD in a 70-year-old woman with septic arthritis on the right knee.
