title: Histopathologic features of the spontaneous pustular lesions of Behçet's syndrome.
abstract: BACKGROUND
  Papulopustular lesions are common in Behçet's syndrome (BS). A debate exists as to whether they are different from ordinary acne. This has important clinical and pathophysiologic implications.
  
  
  OBJECTIVE
  The aim of this study was to evaluate the histopathologic features of papulopustular lesions seen both in BS and acne vulgaris (AV).
  
  
  METHODS
  Representative samples were obtained from 17 patients with BS and six patients with AV. The detailed histopathologic features were evaluated by a dermatopathologist blinded to the diagnoses.
  
  
  RESULTS
  Considering the epidermis, follicle epithelium, and dermis separately, no differences could be found between the two groups.
  
  
  CONCLUSIONS
  The papulopustular lesions seen in these two disorders cannot be distinguished on the basis of clinical and histopathologic findings.
