Introduction: Ovarian cancer accounts for 6% of all cancers in females and is the fifth most common form of cancer in women in USA. The complex nature, unpredictable behaviour and prognosis make ovarian tumour a difficult problem for the gynaecologist. The histogenesis of many tumours are interrelated and accurate histopathological diagnosis is needed for affective treatment. Aim: to determine various histopathological variants of ovarian tumour and their age distribution in south east region of Rajasthan. Method: The study included cases of ovarian neoplasm received at the histopathology section of the department over one and half year period from January 2016 to June 2017. All ovarian cases including incisional and excisional biopsies as well as hysterectomy with unilateral /bilateral salpingoopherectomy specimens from clinically suspected ovarian neoplastic lesions were included in the present study. It was carried out in the Department of Pathology, Geetanjali medical college and hospital Udaipur. Results: Majority of the ovarian tumours belonged to benign (66.92%) followed by malignant tumours (28.46%). Based on the microscopic features, the tumour were broadly classified into various groups as per WHO classification of ovarian tumours were commonest (76.12%), followed by by Germ cell tumour (18.46%). Conclusion: Benign tumors are more common than malignant ones for all diverse age groups. Surface epithelial tumors are most common class of tumors, benign surface epithelial tumors being most common benign tumors and malignant surface epithelial tumors being most common malignant tumors.
