title: Sweet syndrome and pemphigus vulgaris.
abstract: BACKGROUND
  Pemphigus vulgaris is an autoimmune blistering disease of the skin and mucous membranes. Sweet syndrome is an uncommon reactive neutrophilic dermatosis.
  
  
  OBJECTIVE
  This case report describes the rare presentation of a 58-year-old female patient with newly diagnosed pemphigus vulgaris who later presented with erythematous plaques and leukocytosis highly suggestive of Sweet syndrome.
  
  
  METHODS
  Review of the literature using the PubMed and Medline databases.
  
  
  RESULTS
  The clinical presentation of new-onset Sweet syndrome in a patient with pemphigus has been reported in the literature only on one other occasion.
  
  
  CONCLUSIONS
  The observation of an association between Sweet syndrome and autoimmune diseases, such as pemphigus vulgaris, may ultimately lead to better understanding of the pathophysiology of this disease.
