title: Tubulovillous adenoma of the vulva.
abstract: BACKGROUND
  We report the second case of enteric-type villous adenoma of the vulva. The differential diagnosis, histogenesis, and pathogenesis are discussed.
  
  
  METHODS
  A 66-year-old woman had a tumor resected from the posterior aspect of the vulva. The tumor was characterized by its villous architecture, with columnar epithelium and goblet cells. This vulvar tubulovillous adenoma was identical to a tumor resected 6 months before from this patient's rectal wall.
  
  
  CONCLUSIONS
  These two tumors behaved benignly, and the vulvar adenoma possibly originated with the müllerian vestige.
