Childhood immunobullous disease following a second organ transplant

Immunobullous diseases are quite unusual in children. We report two children who developed immunobullous disease shortly after a second solid organ transplantation. One child had IgA pemphigus vegetans, the other bullous pemphigoid. We hypothesize that the repeat organ transplantation served as a "booster" immunization for autoantibody production. Both children developed their immunobullous condition while being treated with immunosuppressive drugs that are used to treat immunobullous disorders.
