Distribution & Histopathological Study of Various Types of Ovarian Tumors: An Institutional Study

Background & Objectives: Ovarian tumors are one of the most common tumors, which occur in female genital tract. Despite the newer techniques in imaging and molecular biology, the diagnosis of ovarian tumors primarily depends on histopathological examination. This study describes the distribution, clinical and histopathological details of various ovarian tumors in a tertiary care center in Maharashtra, and to find out the incidence of benign and malignant ovarian tumors. Materials and methods: This study includes all the ovarian tumors sent to the Department of Pathology at MGM Medical College, Aurangabad. A prospective study of 2 years as well as retrospective study of 2years was done. The correlation of these tumors was done with age, clinical presentation and histomorphological patterns. The data from retrospective study and prospective study was compared. Results: A total number of 112 cases were studied. Out of these 86 were benign and 26 were malignant. Maximum cases were seen in 21 to 30 years. The maximum number of benign tumors belonged to surface epithelial type, of these serous cysadenoma (38 cases) were common followed by mucinous cystadenoma(16 cases). Second largest group was formed by mature teratoma(28 cases). 2 case each of fibrothecoma and lipid cell tumor were noted. Malignant tumors like serous cystadenocarcinoma formed 8 cases out of which 2 cases showed metastasis to rare sites like cervix and appendix and 2 cases coexisted with stromal sarcoma of the uterus, granulosa cell tumor formed 10 cases and 4 cases each of dysgerminoma and endodermal sinus tumor were noted. Conclusion: In the study majority (77%) of ovarian tumors were benign. Malignancy was seen in 23% of the cases. Correct histopathological diagnosis of ovarian tumors is of prime importance in view of their behavioral predictability and clinical correlation for proper management of the patient.
