Background:Ovaries are one of the commonest sites of neoplastic lesions. Ovary is complex in its embryology, histology, steroidogenesis and potential for malignancy and presents wide variation in the clinical and morphological features The clinical stage of the neoplasm per se is inadequate to evaluate the optimum mode of therapy and to compare the therapeutic results. Histological classification of ovarian tumors forms an integral part of this evaluation Determination of various histopathologic patterns of ovarian tumors is very important in diagnosis as well as prognosis of ovarian tumors.Aims and Objectives: To classify and to study the histomorphology of various types of benign, borderline and malignant ovarian tumors and their relation to age and distribution of ovarian neoplasm.
