ENDOMETRIAL PATTERNS IN ABNORMAL UTERINE BLEEDING A STUDY OF 300 CASES IN A TERTIARY CARE HOSPITAL IN SOUTH INDIA.

Background: Abnormal uterine bleeding (AUB) is defined as changes in frequency of menstruation, duration of flow or amount of blood loss. Abnormal uterine bleeding (AUB) is the commonest presenting symptom in Gynaecology outpatient department. Endometrial sampling could be effectively used as a first diagnostic step in abnormal uterine bleeding. The aim of the study was to analyze the histomorphological patterns of endometrium in patients presenting with abnormal uterine bleeding and also to determine the incidence of abnormal uterine bleeding in various age groups. Materials and Methods: All cases of abnormal uterine bleeding with a probable endometrial cause received in the Department of Pathology, Saveetha Medical College, Chennai for a period of 12 months from January 2016 to January 2017 were included in this retrospective study. Data was analyzed using Statistical Package for the Social Sciences (SPSS) version. Results: The most common age group presenting with abnormal uterine bleeding was 18-40 years. The commonest non organic lesion was proliferative endometrium (39%),followed by secretory pattern (24%),while in organic lesions the most common cause of abnormal uterine bleeding was pregnancy related. Conclusion: The cases were clustered around perimenopause. Histopathological evaluation of endometrial samples is highly helpful especially in women over the age of 40 years to rule out premalignant and malignancy lesions of endometrium.
