ObjectiveTo determine agreement of preoperative and postoperative histopathology of endometrial hyperplasia (EH).Materials And MethodsHistopathology 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.ResultsOf 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.ConclusionsFor 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.
