Exploring Morphometry of Endometrial Glands and Blood Vessels in Reproductive Age Women With Abnormal Uterine Bleeding

Abstract

Background Abnormal uterine bleeding (AUB) is one of the most common problems encountered in gynaecological practice. Defective endometrial angiogenesis has been implicated in various benign and malignant disorders of the endometrium. Aim This study aims to assess morphometry of endometrial glands and blood vessels in patients with AUB. Material and methods This is a one year retrospective cross sectional analysis of endometrial samples received with the diagnosis of AUB in reproductive age group. All samples were routinely processed and stained. Sections were analysed for morphometry of blood vessels and endometrial glands. Results A total of 374 cases were included. Most common histological group was proliferative followed by secretory phase. A significant difference was noted in mean vascular density, diameter, mitotic scores and height of glandular epithelium in different benign and malignant groups. Conclusion This study highlights the fact that glandular and vascular morphometry can be used to differentiate between various proliferative disorders of the endometrium. In the current era of new anti-angiogenic therapies, endometrial angiogenesis and changes in vascular morphology can be targeted, thus improving treatment modalities and patient care.
