title: Prurigo pigmentosa: an underdiagnosed disease in patients of Iranian descent?
abstract: BACKGROUND
  Prurigo pigmentosa (PP) is a rare inflammatory disease of the skin typified by recurrent, pruritic erythematous macules and papules that resolve leaving behind netlike pigmentation.
  
  
  OBJECTIVE
  PP is diagnosed most commonly in Japanese women. Preponderance of the disease in other ethnic populations has yet to be identified.
  
  
  METHODS
  We conducted a clinicopathologic case study in 4 Iranian women.
  
  
  RESULTS
  The clinical diagnosis of PP was confirmed by typical histopathologic findings, elucidating the morphologic spectrum of the disease.
  
  
  CONCLUSIONS
  The small number of patients in this study is a limitation.
  
  
  CONCLUSIONS
  We suspect that PP may have a proclivity in the Iranian population.
