title: Arteriovenous malformation of the vulva: a case report.
abstract: OBJECTIVE
  To report the case of a patient with a large and symptomatic vulvar lesion, necessitating surgical excision.
  
  
  METHODS
  We report the case of a 57-year-old postmenopausal woman with a 6-month history of an enlarging vulvar lesion associated with vulvar pruritus. On examination, a pedunculated 7 × 5 × 4-cm soft tissue mass attached to the left labium majus was noted. Surgical excision was performed and histopathologic evaluation revealed variably dilated, submucosal vessels with thick muscular walls and intimal thickening, but without endothelial atypia or multilayering. These findings were consistent with a final diagnosis of arteriovenous malformation of the vulva.
  
  
  CONCLUSIONS
  Given the complex anatomy of the vulva, the differential diagnosis for vulvar vascular lesions can be challenging. Hence, surgical excision and histopathologic evaluation become imperative to distinguish them from other dermatologic and neoplastic conditions of the vulva.
