Paraneoplastic pemphigus is a form of pemphigus associated with malignancy. Positive paraneoplastic pemphigus sera give immunofluorescence reactions not only of pemphigus antibodies, but also react with other epithelia. Thus serum tests for this suspected condition are performed on an additional substrate.
