title: Pemphigus vulgaris preceded by herpetiform-like skin lesions with negative immunofluorescence findings.
abstract: We report a case of pemphigus vulgaris in a 63-year-old woman. At the first onset, she developed herpetiform-like skin lesions. Their histology showed eosinophilic spongiosis and intraepidermal blister formation with an infiltrate of eosinophils. Both direct and indirect immunofluorescence studies were negative. She remained in remission for 6 years. At the second onset, she developed bullous skin lesions; histological examination disclosed suprabasal acantholysis and infiltration of eosinophils. Direct immunofluorescence revealed IgG and C3 deposits at the cell surface, predominantly in the lower epidermis. Indirect immunofluorescence using normal human skin as a substrate demonstrated anti-cell surface IgG antibodies at a titer of 1:160. Immunoblot analysis showed that the patient's serum reacted only with a 130 kD protein. This case indicates that pemphigus vulgaris can follow herpetiform-like skin lesions with negative immunofluorescence findings after a long remission time.
