[Erythromelanoderma in pemphigus herpetiformis associated with eosinophilic spongiosis]

A 62 year old female was treated for several years with DDS because of Duhring-disease like symptoms. She developed erythro-melanoderma, generalized lymphadenitis and pachyderma. Histologically there were eosinophilic spongiosis and intraepidermal vesiculation, blood eosinophilia up to 42%, and intercurrent streptococcal septicemia, immunohistologically in vivo bound pemphigus antibody, but no papillary or linear IgA. Indirect immunofluorescence was negative. Paraproteinemia was excluded.
