Pemphigus vegetans of the folds (intertriginous areas)

Pemphigus vegetans (P Veg), the rarest form of pemphigus, is thought to be a variant of pemphigus vulgaris (PV). Classically, two subtypes of P Veg are recognized: (1) Neumann P Veg, which usually begins as PV with vesicles and bullae that rupture to form hypertrophic granulating erosions, then evolving into vegetating exuding masses; (2) Hallopeau P Veg, initially characterized by pustular lesions that, after rupturing, merge and gradually evolve into vegetating erosions with a centrifugal expansion.
