Endometrial Histology in Epithelial Ovarian Tumors: A Critical Analysis

Objective:The aim of the present study is to determine the prevalence of abnormal endometrial histology, premalignancy, and malignancy in women diagnosed with epithelial ovarian tumors and tumor-like conditions (PCOS, endometriosis, stromal hyperplasia, and stromal hyperthecosis).Materials and methods: Endometrial and ovarian specimens of 71 patients with epithelial ovarian tumors were retrospectively selected, and the histopathology was analyzed.Moreover, 79% had serous tumors, 15.4% had mucinous tumors, and 5.6% other tumors (fibrothecoma, cystadenofibroma).Ovarian histopathology was compared with the concurrent endometrial pathology.Results: Among the samples analyzed, 41% had abnormal endometrial histology, of which 29% is polypoidal endometrium and 12% is disordered proliferation, both of which represent hyperestrogenic state.Conclusion: Abnormal endometrial histology due to stromal steroidogenesis and its biological action on endometrium is well-known; hence, endometrial evaluation is mandatory for planning treatment and understanding the disease process of epithelial ovarian tumors.
