Abstract Introduction: Dysfunctional uterine bleeding is the commonest presenting symptom in gynaecology outpatient department. Endometrial sampling could be effectively used as the first diagnostic step in the DUB. This study was done to evaluate histopathology of endometrium for identifying the endometrial causes of DUB. We also tried to observe the incidence of various pathologies in different age groups presenting with abnormal uterine bleeding. Material and methods: This is a prospective study undertaken in the Dept of OBGY, Indian Institute of Medical Science and Research, Warudi, Jalna. 80 cases of DUB were included in this study. Endometrium specimen were obtained by D and C. Result: The most common age group presenting with DUB was 41-50 years (50%). The commonest pattern in these patients was proliferative endometrium. The commonest pathology was simple cystic hyperplasia. Menorrhagia was the commonest bleeding pattern. As age advances, incidence of hyperplasia was increased. Parity had no influence on endometrial pattern in DUB. Conclusion: There is an age specific association of endometrial bleeding with highest incidence in perimenopausal age group. Dialatation and curettage is helpful to exclude other organic pathology which mimic DUB like endometrial polyp, endometritis, etc. It is useful for diagnosis, to assess therapeutic response and to know the pathological incidence of organic lesions in cases of dysfunctional uterine bleeding prior to surgery.
