title: Case report of Zenker's diverticulum in identical twins: further evidence for genetic predisposition.
abstract: OBJECTIVE
  We report identical twins with Zenker's diverticulum.
  
  
  METHODS
  Case report and literature review.
  
  
  CONCLUSIONS
  Geographical and racial variation in occurrence, and rare familial cases, suggest that inherited factors play a role in the pathogenesis of Zenker's diverticulum. The identical twins reported here provide further evidence supporting a genetic predisposition.
