Evaluation of Endometrial Histopathology of Patients Presenting with Abnormal Uterine Bleeding

Objective: Abnormal uterine bleeding is an important symptom frequently encountered in the gynecology outpatient clinic. In our study, it was aimed to determine the endometrial pathologies that cause abnormal uterine bleeding. Material and methods: The pathology results of patients who applied to our clinic with the complaint of abnormal uterine bleeding and underwent endometrial sampling were retrospectively analyzed. Findings were classified and compared according to whether the patients were in the postmenopausal or premenopausal period. Results: A total of 878 patients were included in the study. The mean age of the patients was 47.59±7.91/year. The most common symptom was menometrorrhagia 58.1%. The most common pathological finding was endometrial polyp in both premenopausal and postmenopausal patients (29.69% and 24.31%). The incidence of premalignant and malignant lesions was 2.7% in premenopausal patients and 8.25% in postmenopausal patients. Conclusion: Abnormal uterine bleeding may be associated with malignancies in both postmenopausal and premenopausal patients. Performing endometrial sampling in patients presenting with this symptom is of great importance in providing early diagnosis and treatment of malignant and premalignant lesions.
