PEMPHIGUS ASSOCIATED WITH NAIL DYSTROPHY

Two patients suffering from PemPhigus vulgaris were found to have nail dystrophies which antedated the onset of mucocutaneous lesions by many years. The nail changes improved substantially on treatment of the bullous disease. One patient had nail matrix histology consistent with pemphigus, and both had positive direct immunofluorescence with intercellular IgG in the matrix epithelium, as well as at other body sites. We propose that dystrophic nails, as a non-specific indicator of autoimmune disease, are a genuine and relevant finding in pemphigus.
