title: Pseudoangiomatous stromal hyperplasia of the vulva presenting as a polypoid vulvar lesion: a lesion associated with anogenital mammary-like tissue-report of a case and review of the literature.
abstract: OBJECTIVE
  The study aimed to report the case of a patient with a polypoid vulvar lesion clinically thought to be an aggressive angiomyxoma.
  
  
  METHODS
  On examination, a 4.0 × 2.0 × 1.5-cm polypoid lesion was seen on the right labium majus.
  
  
  RESULTS
  Histopathological findings of the excised mass were consistent with pseudoangiomatous stromal hyperplasia of the vulva
  
  
  CONCLUSIONS
  Pseudoangiomatous stromal hyperplasia is a lesion of breast tissue but can occur in anogenital mammary-like glands. It must be distinguished from low-grade angiosarcoma.
