De novo Pemphigus Vegetans

Abstract

Pemphigus vegetans is an autoimmune disease characterized by flaccid bullae or pustules that erode to form hypertrophic plaques involving predominantly skin flexures and mucous membranes [1]. We are presenting an unusual case of de novo pemphigus vegetans with extensive involvement of genitals, perianal area, buttocks, nails, oral mucosa, and cerebriform tongue which was initially mistaken for malignancy due to its unusual presentation.
