©2012 by Anais Brasileiros de Dermatologia In the November/December 2011 issue of the Anais Brasileiros de Dermatologia (Brazilian Annals of Dermatology), Adriano et al. reported a case of druginduced pemphigus vegetans (PV). We congratulate the authors on the thorough documentation of the patient as well as on the detailed discussion of the topic. However, we would like to emphasize the import...

Pemphigus vegetans is a rare variant of pemphigus vulgaris and is characterized by vegetating lesions in the inguinal folds and mouth and by the presence of autoantibodies against desmoglein 3. Two clinical subtypes of pemphigus vegetans exist, which are initially characterized by flaccid bullae and erosions (the Neumann subtype) or pustules (the Hallopeau subtype). Both subtypes subsequently d...

Pyodermatitis-pyostomatitis vegetans is a rare, polymorphous inflammatory disorder of the skin and oral mucosa first described by Hallopeau in 1898. On the skin papules, pustules and reddish brown annular vegetating plaques develop, most frequently in the intertriginous areas. In the mouth, yellowish flat ulcerations arise, typically in the shape of "snail tracks". The association with inflamma...

Pemphigus vegetans is a clinical variant of pemphigus vulgaris, accounting for 1-2% of all very rare pemphigus cases in children. The involvement of the oral mucosa in this disease is usually accompanied by severe pain that aggravates the patient's malnourished condition. Conversely, malnutrition may also reduce vulnerability towards autoimmune diseases. Although pemphigus vegetans has never be...

IMPORTANCE Pemphigus vegetans shows clinically vegetating and/or pustular skin lesions mainly on the intertriginous areas and histopathologically neutrophilic and eosinophilic pustules in the epidermis. Pemphigus vegetans shows IgG reactivity mainly with desmoglein (Dsg) 3, but also with other autoantigens, including Dsg1 and desmocollins (Dscs). OBSERVATIONS We examined antigen profiles in 2...
