Distribution of various histopathological types of ovarian tumors: A study of 212 cases from a tertiary care center of Eastern Uttar Pradesh

Abstract

Abstract BACKGROUND: Ovarian tumors are one of the leading cancers in females with variable pathological types. This study describes the distribution, clinical and pathological details of various histopathological types of ovarian tumors in a tertiary care hospital in North India. MATERIALS AND METHODS: A retrospective data of 3 years were collected for ovarian tumors submitted to the pathology department of a tertiary care hospital. Data were classified according to the latest World Health Organization (WHO) Classification into epithelial tumors, germ cell tumors, sex cord–stromal tumors, and others. RESULTS: A total of 212 cases of ovarian tumors were studied, 186 were unilateral and 26 were bilateral. Resection specimen, part of specimen, and block review formed 80.2%, 15.1%, 4.7%, respectively. Epithelial tumors formed the majority in 71.7% of cases followed by germ cell tumors (22.2%), sex cord–stromal tumors (3.8%) and others (2.3%). Maximum number of cases in the respective groups occurred in the age groups 31–40, 21–30, 51–60, and 41–50 years, respectively. Overall, benign tumors were 63.7%, malignant tumors were 31.1%, and borderline were 5.2%. The most common histopathological type of benign and malignant tumor was benign serous cystadenoma (18.8%) and serous carcinoma (9.9%), respectively. CONCLUSION: In the present study, ovarian tumors were classified according to the WHO classification, epithelial and germ cell tumors were the major types of ovarian tumors. Benign epithelial tumor formed the majority with 46.2% cases. Serous cystadenoma and mature cystic teratoma were the predominant type of epithelial and germ cell tumors, respectively.
