Differentiating Pemphigus Foliaceus From Pemphigus Vulgaris in Clinical Practice

Abstract

Pemphigus is a skin condition that causes intraepidermal separation of keratinocytes. Multiple types of pemphigus exist, including pemphigus vulgaris and pemphigus foliaceus. These can be differentiated by histopathology, clinical presentation, appearance of lesions, and antibodies, among other factors. It is important to distinguish between the two because of differences in management and prognosis. Here we present a case of pemphigus foliaceus, as well as a discussion of the key differences between pemphigus foliaceus and vulgaris.
