title: Accessory uterine appendage may be a new Müllerian malformation.
abstract: OBJECTIVE
  To describe a case of an accessory uterine structure.
  
  
  METHODS
  Case report.
  
  
  METHODS
  University affiliated, community-based hospital.
  
  
  METHODS
  A 35-year-old woman who presented for laparoscopic tubal sterilization.
  
  
  METHODS
  Laparoscopy, tubal sterilization, dye test, and excision of accessory uterine structure.
  
  
  METHODS
  Laparoscopic findings and resection of the anomaly.
  
  
  RESULTS
  Laparoscopy showed a hollow uterine appendage that communicated with the uterine cavity. This was completely excised.
  
  
  CONCLUSIONS
  We report a rare case of a uterine anomaly that is inconsistent with the traditional classification system, and we offer a possible mechanism for its formation.
