Linear IgA dermatosis in an immunosuppressed patient after allogenic bone marrow transplantation

Linear IgA dermatosis (LAD) is a well‐recognized acquired subepidermal bullous autoimmune disease. LAD is characterized by clinical, histopathological and immunopathological findings. We report the case of a 38‐year‐old man who suffered from a chronic myeloic leukaemia. Although he received immunosuppressive therapy he developed LAD after an allogenic bone marrow transplantation. After diagnosis of LAD was established we started a successful systemic therapy with dapsone, while continuing the preliminary medication. Here we report for the first time on a possible relationship between LAD and bone marrow transplantation in an immunosuppressed patient.
