Aim: Investigation of endometrial pathology in cases of abnormal uterine bleeding within a tertiary care hospital. Material and methods: The present study consisted of a cohort of 120 individuals who exhibited a clinical diagnosis of Abnormal Uterine Bleeding (AUB). The inclusion criteria for this study consisted of patients who had isolated endometrial pathology and presented with a clinical diagnosis of abnormal uterine bleeding (AUB). The age of the patients, their clinical presentation, examination findings, and details of the surgical procedures they underwent were documented based on requisition forms and hospital records. Results: A total of 120 cases were included in this study. The age of patients ranged from 20 to 80 years. Maximum numbers of patients were in the age group 40 -50 years (50%). The predominant histological pattern observed was Secretory phase 28 (23.33%), Followed by Hyperplasia without atypia 26 (21.67%), Disordered proliferative 20 (16.67%), Atrophic phase 14 (11.67%), Proliferative phase 11 (9.17%), Basal endometrium 9 (7.5%), Gestational 4 (3.33%), Pill endometrium 3 (2.5%), Hyperplasia with atypia 2(1.67%) and Endometrial carcinoma 2(1.67%) and Menstrual phase 1(0.83%). Conclusion: Age-related pathology is a contributing factor to abnormal uterine bleeding (AUB) of endometrial origin. The gold standard for evaluating abnormal uterine bleeding (AUB) is histopathological examination of the endometrium. The precise evaluation of endometrial sampling plays a crucial role in facilitating optimal therapeutic interventions. Keywords: Endometrial, Abnormal Uterine Bleeding, Histopathology
