Background/Aim. The prevalence of endometrial polyps (EPs) in the general female population is about 24%. Abnormal uterine bleeding is frequently the presenting symptom of EPs. The aim of this study was to determine the prevalence and characteristics of EPs in patients with abnormal uterine bleeding. Methods. The prevalence and characteristics of EPs were investigated in 961 patients with abnormal uterine bleeding who underwent dilatation and curettage between January and December 2006. Regarding histopathological features of EPs (presence of atypical hyperplasia or endometrial carcinoma), patients were divided into two groups: group A - patients who had EPs and EPs with hyperplasia without atypia (n = 204) and group B - patients who had EPs with atypical hyperplasia and EPs with carcinoma (n = 7). Results. In 211 (21.94%) patients EPs were found with abnormal uterine bleeding. Histopathologically, there were 175 (82.94%) EPs, 29 (13.74%) EPs with hyperplasia without atypia, 5 (2.37%) EPs with atypical hyperplasia, and 2 (0.95%) EPs with endometrial carcinoma. Contrary to the patients with EPs and EPs with hyperplasia without atypia (group A), patients who had EPs with atypical hyperplasia and EPs with carcinoma (group B) were older (p < 0.05), and more commonly postmenopausal (p < 0.05) and with hypertension (p < 0.05), all of statistical significance. Conclusion. The prevalence of endometrial polyps in patients with abnormal uterine bleeding according to our data was 21.95%. Atypical hyperplasia and endometrial carcinoma were rarely confined to a polyp. Older age, postmenopausal period and hypertension may increase the risk of premalignant and malignant changes in endometrial polyps.
