In utero development of epidermolysis bullosa acquisita

Abstract We report the case of an infant born with perioral vesicles that rapidly spread to involve his mouth and the majority of his body. Histopathology, immunofluorescence, and enzyme‐linked immunohistochemistry assays confirmed a diagnosis of epidermolysis bullosa acquisita ( EBA ). His mother had no history of EBA , and serum indirect immunofluorescence was negative. The patient improved rapidly with local wound care and oral dapsone.
