Introduction: Ovarian cancer accounts for 3% of all cancers in females. About 80% of these are benign, and they occur mostly in young women between 20 and 45 years. Borderline tumors occur at slightly older ages while incidence of malignant tumors increases with age, occurring predominantly in perimenopausal and postmenopausal women. About 190,000 new cases and 114,000 deaths from ovarian cancer are estimated to occur annually worldwide. The aim of the study was to evaliuate the spectrum of surface ovarian tumor in a tertiary referral centre. Material and methods: This was a hospital based cross sectional observational study conducted for one year from 1st June 2019 to 31st May 2020 in the Department of Pathology, Indira Gandhi Medical College, Shimla. Results: On histological examination, majority of epithelial ovarian tumors were benign 38 (50%) followed by malignant 32 (42.1%) and borderline tumors 6 (7.9%). Serous (47.4%) and mucinous cystadenomas (44.7%) constituted the predominant group among benign tumors followed by Brenner tumors (7.9%). Borderline tumors comprised of 4 atypical proliferative mucinous tumors (APMT) and 2 atypical proliferative serous tumors (APST). Malignant tumors comprised 32 out of total 76 cases. Amongst them Serous carcinoma constituted 71.9% of total cases followed by 12.5% endometroid carcinomas, 9.4% mucinous carcinomas and 1 case each of malignant Brenner tumor and clear cell carcinoma. Conclusion: In our study, in both benign and malignant cases, serous tumor was the commonest followed by mucinous tumors.
