Summary:We report a clinical case of a rare variant of pemphigus - pemphigus herpetiformis - which combines the clinical features of dermatitis herpetiformis with the immunological findings of pemphigus. Due to its atypical presentation, it is frequently misdiagnosed as dermatitis herpetiformis. It is basically characterized by the herpetiform pattern of skin lesions, severe pruritus and by the presence of eosinophilic spongiosis confirmed on histopathology. We call attention to the excellent response to dapsone.<br>Descrevemos um caso clínico de uma variante rara de pênfigo - pênfigo herpetiforme - que combina os aspectos clínicos da dermatite herpetiforme com os achados imunológicos do pênfigo. Devido à sua apresentação atípica, é frequentemente diagnosticado equivocamente como dermatite herpetiforme. Caracteriza-se essencialmente pelo padrão herpetiforme das lesões cutâneas, prurido intenso e presença de espongiose eosinofílica no exame histopatológico. Enfatizamos a excelente resposta terapêutica à dapsona.
