Introduction: Ovarian lesions are commonly encountered lesions of diverse morphological spectrum that may develop from neonatal period to post-menopause. They are amongst the most frequent cause of hospitalization and surgery in gynaecological practice. Distinguishing non-neoplastic lesion from a neoplastic lesion on the basis of clinical, radiological or gross characteristics alone is a challenge, thus histopathological examination is must as it is also important in guiding therapy. Objectives: This study was undertaken to study the various histopathological patterns of ovarian lesions, their classification and relative distribution of these lesions. Material and Methods: This is a retrospective study of ovarian lesion specimen that was received in the Histopathology section of our department over a period of 5 years from January 2013 to December 2017. Results: A total of 190 cases of ovarian lesions were included in this study with age range from 14 years to 75 years. 106 were non-neoplastic and 84 were neoplastic in nature. Functional cyst including Corpus luteal cyst was the commonest non-neoplastic lesion (26 cases) followed by 21 cases each of endometriotic cyst and simple cyst. Out of 84 neoplastic lesions, 74 were benign, 3 were Borderline and 7 were malignant in nature. Serous cystadenoma was the commonest benign lesion and Serous carcinoma was the most common malignant tumor in our study. Conclusions: Ovarian lesions comprises of wide spectrum of lesions and their presenting clinical, radiological and gross features are very similar. Hence Histopathology forms the mainstay of definitive diagnosis and categorization of these lesions.
