RESUMO
To evaluate the frequency and types of ovarian tumours with respect to age. 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. 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% 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 5th and 6th decades. In this study surface epithelial tumours were the major histological type of ovarian tumours followed by germ cell tumours
