title: [Pemphigus erythematosus].
abstract: Pemphigus erythematosus, also known as Senear-Usher syndrome, was originally described as a variant of pemphigus with features of lupus erythematosus but regarded today as a localized form of pemphigus foliaceus and considered an autoimmune bullous disease. The autoantigen is desmoglein 1, a desmosomal adhesion protein in keratinocytes. A 69-year-old man presented with a 3-month history of erosions and blisters on the cheeks, which then also appeared on the trunk. Clinical and histopathologic criteria as well as immunofluorescence studies lead to the diagnosis of pemphigus erythematosus with transition to pemphigus foliaceus.
