AbstractIntroduction: Adnexal masses are most common disease in gynaecology of which ovarian tumors represent 2/3rd of these cases. Ovarian lesionscan be present in any age group and also present in a wide spectrum of histomorphogical patterns. Many ovarian tumours are asymptomatic in the early stages and are unfortunately diagnosed in the advanced stage. The diagnosis of ovarian tumor helps to plan the treatment modality like chemotherapy, radiotherapy and surgery depending upon stage of the tumor and age of the patient. Materials and Methods: This is a prospective study of 85 ovarian lesions at tertiary care hospital within one year period. The specimens of ovarian masses sent from gynaecological departmentare processed by routine paraffin techniques. Microscopic examination was done on sections stained with Haematoxylin and Eosin. Result: The total 85 cases of ovarian neoplasms were studied during study period, out of which 45 were non-neoplastic lesions and 40 lesions were neoplastic. Follicular cysts were the commonest non-neoplastic lesion; 27 cases (60%), followed by endometriosis 11 cases (24.44%). Out of the 40 neoplastic ovarian lesions benign cases were 28 (70%), borderline cases were 3 (7.5%) and malignant cases were 9 (22.5%). Mucinous cystadenoma, followed by serous cystadenoma were most common lesions in benign neoplasm and serous cyst adenocarcinoma was the most common malignant lesion. Conclusion: Tumor-like lesions are more common than ovarian tumors mimicking ovarian neoplasm which manifest a variety of gross and histological features. Their histopathological study is still the gold standard method in diagnosing most of the ovarian lesions.
