Background: Ovarian tumors are the common forms of neoplasms in women. Ovarian cancers has the worst prognosis, because they are asymptomatic in early stages and are often detected at later stages. Aim: To determine the incidence, age wise distribution of ovarian neoplasms and also to classify the ovarian neoplasms based on the histomorphological pattern. Materials and Methods: This study was done in the Department of Pathology, Narayana medical college and Hospital, Nellore, AndhraPradesh, India for a period of two years from January 2016 to December 2017.Total 110 cases of ovarian neoplasms were studied. Results: Out of total 110 cases, 90 cases (81.81%) were benign, 16 cases (14.54%) were malignant and 4 cases (3.63%) were borderline. Ovarian tumors were more common in 31-40 years age group. The most common presenting symptom was abdominal pain (46.5%). Surface epithelial tumors were the commonest, accounting for 80 cases (72.72%). Most of the ovarian tumors were cystic (75.45%). About 94.3% of tumors were unilateral. Conclusion: In our study, most common ovarian tumors are surface epithelial tumors. Benign tumors are common in the young age, whereas malignant tumours are common in the post menopausal age group. As most of the tumors are diagnosed in late stages, early diagnosis of ovarian tumors is necessary, so as to decrease the morbidity and mortality.
