Background: The present study was conducted for evaluating histopathological findings in patients with abnormal uterine bleeding. Materials & methods: A total of 100 cases were enrolled. Well preserved endometrial tissue from females with AUB were enrolled. Inadequate and autolyzed specimens of endometrium were excluded. Details of the study protocol was explained to the subjects. Complete History was taken. Information on regularity of the menstrual cycles was taken. Endometrial curettage samples was fixed in 10% formalin and histopathological slides were prepared and stained with hematoxylin and eosin stain. Slides were examined under microscope to confirm the cause of AUB. All the results were analysed by SPSS software. Results: Normal/hormonal histopathologic findings were seen in 36 percent of the patients while hyperplasia was seen in 6 percent of the patients. Polyps were seen in 22 percent of the patients (Endometrial polyp – 7 percent; Cervical polyp – 15 percent). Endometrial carcinoma was present in 6 percent of the patients while cervical carcinoma was seen in 5 percent of the patients. Collectively, malignancies were present in 11 percent of the patients. Conclusion: Normal cyclic changes account for the highest proportion of histopathological findings. However, malignancies are important causes of AUB.
