Frequency and pattern of ovarian tumours
Abstract
Objective: To evaluate the frequency and types of ovarian tumours with respect to age.
Methodology: All the ovarian tumours which were diagnosed in the Department of Pathology, Muhammad Medical College Hospital Mirpurkhas over a five years period from January 2005 to December 2009 were reviewed.
Results: A total of 227 cases were reviewed. 181 lesions were found benign tumours and 46 were malignant. Surface epithelial tumours were common benign tumours and consist of serous cyst adenoma with a frequency of 55% followed by mucinous cyst adenoma 20%. Benign germ cell tumours was 25%. In malignant tumours, serous cyst adenocarcinoma was the commonest malignant lesion 38% followed by 17% cases of mucinous cyst adenocarcinoma and one (2%) case of clear cell carcinoma. Germ cell tumours were composed of immature teratoma 11%, yalk sac tumour 9%, mixed germ cell tumour 4% & a single case of dysgerminoma with a frequency of 2%. The frequency of sex- cord stromal tumours was 17%. Most of the benign tumours were found in 3rd and 4th decades of life. However maximum number of malignant tumours was seen in 5th and 6th decades.
Conclusion: In this study surface epithelial tumours were the major histological type of ovarian tumours followed by germ cell tumours.
