Frequency and pattern of ovarian tumours

ABSTRACT

To evaluate the frequency and types of ovarian tumours with respect to age. All the ovarian tumours that were diagnosed in the Department of Pathology, over a 5 years period from January 2004 to December 2008 were reviewed. A total of 227 cases were reviewed. 181 lesions were found benign tumours and 46 were malignant. Surface epithelial tumours were common benign consisting consist of serous cyst adenoma with a frequency of 55% followed by mucinous cyst adenoma 20%. Benign germ cell tumours were 25%. In malignant tumours, serous cystadenocarcinoma was the commonest malignant lesion 38%, followed by 17% cases of mucinous cystadenocarcinoma and 1 [2%] case of clear cell carcinoma. Germ cell tumours were composed of immature teratoma 11%, yolk sac tumour 9%, mixed germ cell tumour 4% and 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 3[rd] and 4[th] decades of life. However maximum number of malignant tumours was seen in 5[th] and 6[th] decades. Surface epithelial tumours were the major histological type of ovarian tumours followed by germ cell tumours
