Context: Epithelial cadherin (E-cadherin) is inversely proportional to the histologic grade of squamous cell carcinoma (SCC) of the cervix and is reduced with the increasing grade of cervical intraepithelial neoplasia, with downregulation upon transition to cervical intraepithelial neoplasia and further to invasive cancer. Aims: The aim of the study was to study the expression of E-cadherin in benign and malignant epithelial cervical lesions and to compare the results statistically. Settings and Design: The cross-sectional study was hospital based conducted in the department of pathology from January 2018 to March 2019. Methods: The study was carried out on sixty biopsy specimen of cervix (33 malignant, 4 premalignant, and 23 benign lesions). Two sections were taken; one for hematoxylin and eosin and other for E-cadherin immunohistochemical staining. Statistical Analysis Used: Statistical analysis was done using Chi-square test and Fisher's exact test. Results: In well-differentiated SCC, the majority cases (40%) revealed membranous staining while in moderately differentiated SCC and poorly differentiated SCC, the most common staining pattern was membranous and cytoplasmic (70% and 45.4%, respectively). In adenocarcinoma, 66.6% of cases had membranous pattern of staining, whereas two cases (33.3%) were negative. In High-grade Squamous Intraepithelial Lesion (HSIL), 75% of cases had membranous staining. Pure membranous pattern of staining of E-cadherin showed a progressive decline with a loss of differentiation while pure cytoplasmic revealed a reverse pattern. Conclusions: We concluded that, in malignant lesions, there is a loss of membranous E-cadherin pattern as compared to benign lesions. Furthermore, there is a progressive decline in pure membranous staining of E-cadherin with increase in shift to cytoplasmic staining as differentiation decreases.
