title: Preoperative and postoperative agreement of histopathological findings in cases of endometrial hyperplasia.
abstract: OBJECTIVE
  To determine agreement of preoperative and postoperative histopathology of endometrial hyperplasia (EH).
  
  
  METHODS
  Histopathology of specimens obtained by curettage and hysterectomy within 1 year was retrospectively compared by a skilled gynecological pathologist. Patients who received hormone therapy were excluded.
  
  
  RESULTS
  Of 79 women with a preoperative diagnosis of EH, only 32 were diagnosed as EH from hysterectomy specimens. There was no endometrial cancer. The agreement between preoperative and postoperative histology did not achieve statistical significance (Kappa 0.011). Postoperative histopathology was more severe than preoperative diagnosis in 5 (6.3%) patients, including 3 preoperative diagnoses of simple hyperplasia without atypia, 1 simple hyperplasia with atypia, and 1 complex hyperplasia without atypia.
  
  
  CONCLUSIONS
  For EH diagnosed by curettage, we can be sure of the diagnosis. However, 6.3% had more severe histology from hysterectomy specimens. Thus, repeated curettage or other investigations should be reconsidered in women with recurrent bleeding.
