Context: Ovarian lesions can present in the form of pain in abdomen, mass lesion or infertility. Any age group can be affected. Mass lesions of ovary are important, as they can be neoplastic or non-neoplastic. Appropriate treatment and prognosis is dependent upon the proper classification and diagnosis of ovarian mass lesions, which can be achieved by histopathological examination of excised ovarian tissue. Aims: Present study aims at classifying ovarian lesions histopathologically and finding the frequency of various ovarian tumors. Methods and Material : Present study is a retrospective study carried out at tertiary hospital attached to medical college in rural area of Maharashtra. All oophorectomy specimens received in central clinical laboratory from January 2012 to June 2016 were included in the study. Clinical details were obtained from requisition forms submitted by gynaecology department along with the ovarian specimen sent for histopathological examination. For detail information regarding the case, case sheets were obtained from medical record section of the hospital. Histopathological slides were retrieved from filing and studied blindly by two histopathologists independently. Results thus obtained were compared with original reports and finalized. Results: A total of 152 cases were included in the study. Histopathological examination was performed on 188 ovaries, of which 59 ovaries didn’t show any pathology. Of the remaining 129 ovaries, non-neoplastic lesions were more common (n=85; 65.89%) than neoplastic lesions(n=44; 34.10%). Follicular cysts were commonest amongst non-neoplatic lesions. In neoplastic category benign tumors were more frequent than malignant tumors. Serous cystadenomas were commonest among benign tumors whereas serous cystadenocarcinomas were commonest among malignant tumors. Conclusions: Histopathological examination of excised ovarian tissue forms the mainstay of diagnosis in most of the cases.
