Abstract
Objectives: To study the morphological patterns of different benign and malignant ovarian tumours and their distribution in different age groups in urban population of West Bengal. Review and reclassification of old diagnosed cases of last five years in our department according to the latest WHO classification (2014).
Methods: A retrospective study of all ovarian neoplasms diagnosed in the Department of Pathology, R.G.Kar Medical College and Hospital, Kolkata over a period of five years (July 2012 to June 2017) was conducted. The tumours were reclassified according to the WHO classification of Ovarian tumours (2014). Immunohistochemistry was done in selected cases posing a dilemma in diagnosis.
Results: A total number of 1223 diagnosed cases were studied, 7.11% (n=87) being bilateral. Benign tumours comprised 82.17% (n=1005), borderline tumours 1.07% (n=13) and malignant tumours 16.76% (n=205). Epithelial tumours were the commonest variety accounting for 82.09% (n=1004), followed by germ cell tumours 13.98% (n=171). Serous cystadenoma comprising 46.06% (n=463) and Endometriotic cyst 17.51% (n=176) of the cases were the commonly diagnosed benign tumours. Serous carcinoma and Mucinous carcinoma being the commonest and second most common malignant tumours comprised 64.87% (n=133) and 11.70% (n=24) of the malignant cases respectively. The benign and malignant tumours were most commonly reported in the 3rd and 8th decade of life respectively.
Conclusion: As inferred from this study, ovarian neoplasms both benign and malignant can be specifically categorized into histomorphological subtypes in the light of WHO classification (2014).
Keywords: WHO classification of ovarian tumours (2014); ovarian neoplasms; serous cystadenoma; Endometriotic cyst.
