Abstract :
Background: The female gonad ‘OVARY’ is multifaceted in its histology, embryology, steroidogenesis, and thus has the potential to acquire malignancy. Therefore ovarian neoplasms exhibit a wide variation in structure and biological behaviour. The main objective of our study is to find out the occurrence and distribution of various mass lesions in ovary in our population and to know its histopathological and clinical appearance.
Methods: This study was a retrospective and descriptive study done for a period of 3 years starting from the month of January 2013 to January 2016, at the Obstetrics and Gynaecology Department, Thanjavur Medical College, Tamil Nadu, India. All ovarian tumour cases diagnosed as neoplastic (benign, malignant and metastatic) were incorporated in the study.
Results: Out of 5728 gynaec admissions, 234 (4%) were found to have ovarian tumours. Of these 75.64% (177/234) were neoplastic and 24.36% (57/234) were non-neoplastic lesions. Among 177 neoplasms, the commonest histological pattern observed was epithelial tumours (73.45%).Of these, mucinous tumours (53.07%) were more frequent than serous type (46.92%). Mucinous cystadenoma (62.31%) was the commonest benign ovarian tumour and serous cystadenocarcinoma was the most frequently encountered malignant tumour (60.65%). Germ cell tumours (58%) were the commonest non–epithelial ovarian tumours.
Conclusion: Among the admissions, ovarian neoplasms were more in number than the non-neoplastic ones. Surface epithelial type was the predominant histological type observed and the germ cell tumours were the second commonest type. Mucinous cystadenoma and serous cystadenocarcinoma were the commonest benign and malignant ones respectively. The age of occurrence of malignant ovarian tumour has significantly come down and the predominant symptom was found to be mass abdomen.
