A Case of Epidermolysis Bullosa Acquisita

We report a case of epidermolysis bullosa acqumta with characteristic clinical features, subepidermal vesicles in histopathology, and deposits of IgG in basement membrane zone at routine direct immunofluorescent test. 1M NaCl-treated immunofluorescent test was performed in order to correctly diagnose our case. In this method, linear immunofluorescent deposits of IgG were found only at the dermal part of separation induced by 1M NaC1 treatment to skin specimen.
