Histopathological Patterns of Ovarian Tumours: A Hospital Based Study

Abstract

Background: - Ovary is the site for more than two dozen different tumours with its varied histopathological patterns. Relative frequency of these histopathological patterns is different for Western and Asian countries. Ovarian cancer is one of the most frequent causes of death from gynaecological malignancies. Aims and Objectives: - A hospital based study to determine the histopathological patterns of ovarian tumours. Material and Methods: - The present study is based on the histopathological analysis of 70 specimens of clinically and radiologically diagnosed ovarian tumours presented at Patholgy department of Tezpur Medical College and Hospital, Tezpur, Assam for histopatholcical examination in the period of two years from June 1, 2014 to May 31, 2016. Result and observations: - Out of 70 ovarian tumours, 46 (65.71%) were benign tumour, 2 (2.86%) were borderline and 22 (31.43%) were malignant tumour. Among benign tumours, benign cystic teratoma (30.00%) was the commonest followed by serous cystadenoma (22.86%) and mucinous cystadenoma (8.57%). Among the malignant tumours, the most common type was serous cystadenocarcinoma. Surface epithelial tumour (57.14%) was the commonest tumour according to the histogenesis followed by germ cell tumour (34.29%), sex cord tumours (7.14%) and metastatic tumour (1.43%). The mean age of the subjects was 35.2 years, ranging from 8 to 70 years. Abdominal mass was the most predominant clinical presentation. Conclusion:- Ovarian tumours need histopathological examination for proper diagnosis and follow up of patients. This study gives the histopathological pattern of ovarian tumours of the cases that attended our institute with different clinical presentations. As it is a hospital based study, it might not reflect the exact scenario of the population at large.
