Investigation of the Roles of Cyclooxygenase-2 and Galectin-3 Expression in the Pathogenesis of Premenopausal Endometrial Polyps.

Background: The pathogenesis and etiology of endometrial polyps has not been elucidated. In this study, we aimed to examine the pathogenic mechanisms of endometrial polyp development using immunohistochemistry. We evaluated the expression of galectin-3 and cyclooxgenase-2 (COX-2) during the menstrual cycle in premenopausal women with endometrial polyps or normal endometrium.
