BACKGROUND Ovaries can be afflicted by various lesions, which can be non-neoplastic or neoplastic. Varied spectrum of clinical features and histopathological patterns are seen in these lesions. The present study was done to study the histopathological patterns of ovarian neoplastic and non-neoplastic lesions and their distribution in women of different age groups. METHODS This was retrospective study of all cases of neoplastic ovarian tumours, and nonneoplastic ovarian tumours including functional ovarian cysts received during 5year period from January 2014 to December 2018 in the Department of Pathology of Gandhi Medical College and Hamidia Hospital, Bhopal (M.P.). Data regarding age and tumour histopathology were recorded from pathology records. Routine H/E staining was performed. RESULTS A total of 541 different non-neoplastic and neoplastic lesions of ovaries were seen. Neoplastic tumours were more common (350; 64.6%) than tumour-like lesions of the ovary (191; 35.3%). Non neoplastic ovarian tumours were found to be more common than neoplastic ones in all age groups. Maximum number of ovarian tumours were seen in the age group of 21-50 years (272, 77.7%). Among tumourlike ovarian lesions, the most common were corpus luteal cysts (75, 13.8%). These were found to be more common in the age group of 31-50 years (123, 65%). Surface epithelial tumours were the most common (253, 72.2%) followed by germ cell tumours (70, 12.9%). CONCLUSIONS Neoplastic tumours of ovaries are more common than tumour-like lesions of ovary. For all age groups, benign tumours are more common than malignant ones.
