Ovarian cancer is a leading cause of morbidity and mortality worldwide. Histopathological presentation of ovarian tumours is highly variable which makes it very difficult for early diagnosis and appropriate management. Proper categorization based on morphological histopathological features can aid gynaecologists in better diagnosis and management. Aim: To study the demographic profile of ovarian lesions and to analyze the size, site, grade, and stage of the lesions in a tertiary care centre. Materials and method: This was a retrospective, descriptive and observational study carried out in the Department of Pathology at Saveetha Medical College and Hospital, Chennai. Demographic details and histopathological data from the records of the patients diagnosed with ovarian lesions January 2019 to December 2019 were collected and analysed using SPSS software. Result: Out of the 50 cases, maximum number of cases belonged to the age group 31-40 years (30%) with a mean age of 42.82±15.14 (mean ± SD). Most of the cases during the period of study was unilateral and the most common site of lesion was in the left ovary in 28 (56%) of the cases. With respect to the histological type of the ovarian lesions, surface epithelial tumour type accounted for a majority of 39(78%) of the cases and based on the grade of the tumours, a majority of 23(46%) of the cases was well differentiated. Benign tumours were most common in all histopathological tumour types. Conclusion: Majority of ovarian lesions were benign, unilateral and most commonly occurred in the age group of 31-40 years. On the basis of histopathology, surface epithelial tumours were most commonly seen followed by germ cell tumours. A proper study ofdemographic profile and an exact histopathological categorization is vital for accurate diagnosis and management of the ovarian lesions.
