Histological Patterns of Ovarian Neoplasms – A Five Year Experience in North-East India

Abstract

Background: Ovary is one of the common sites of neoplasm in females. They manifest in wide spectrum of clinical, morphological and histological features. Ovary is the second most common site of primary malignancy in female genital tract. Objectives: To study the frequency of different histological types of ovarian tumors and to analyze age distribution of these tumors. Materials and Methods: This was a retrospective study of all cases of ovarian tumors received at Pathology Department of Agartala Government Medical College during the period of 5 years from January 2012 to December 2016. Results: A total number of 242 cases were studied. Among these 189 cases (78.1%) were benign, 12 cases (4.96%) were borderline and 41 cases (16.94%) were malignant. Benign neoplasms were most commonly seen between 3 rd and 5 th decade of age whereas malignant neoplasms after 4 th decade. Serous cystadenoma was the commonest benign tumor followed by mucinous cystadenoma and mature cystic teratoma. Among the malignant surface epithelial tumors, mucinous cystadenocarcinoma was most common, followed by serous cystadenocarcinoma. Conclusion: Benign ovarian neoplasms outnumber the malignant ones in all age groups. Surface epithelial tumors are the most common class of tumors and mucinous cystadenocarcinoma is the commonest malignant neoplasm.
