Abstract

To evaluate the incidence and clinico-pathologic correlation of benign epithelial changes of endometrium, we tried to classify the changes into squamous cell change, ciliary change, eosinophilic cell change, papillary surface epithelial change, and mucinous cell change by the criteria of Hendrickson. Based on the 450 hysterectomy specimens obtained from Jan. 1994 to Dec. 1994 in PMC, the incidence of the cell changes was as follows: squamous cell change: 1.1%, eosinophilic cell change: 6.8%, mucinous cell change: 6.6%, ciliary change: 10.4%, papillary surface epithelial change: 16.4%. Squamous cell change was noted in severe endometritis or endometrial hyperplasia and papillary surface epithelial proliferation was mainly associated with plasma cell infiltration in adenomyosis or leiomyoma. Eosinophilic change and ciliary change were sometimes concomitantly found in dilated glands of the basal layer or in the invaded glands of adenomyosis. The results of this study suggested a correlation of benign epithelial changes with endometritis, adenomyosis, leiomyoma and dysfunctional uterine bleeding.
