In the last three years 107 postmenopausal women were admitted to Obstetrics and Gynecology Department of the Marmara University Hospital with the diagnosis of "Adnexal mass". Sixty six (63.5%) of 104 adnexal masses were found to be benign tumors and 38 (36.5%) were malignant tumors. 3 tumors of non-gynecologic origin were detected in the same series.The rate of malignancy increases when the adnexal mass is greater than 5 cm. In our series, histologically epithelial tumors constituted 62.1% of benign and 92% of malignant tumors. Postmenopausal women with palpable ovaries were accepted to be under high risk for malignancy and treated as required. Surgical treatment was unavoidable for these patients and always midline incision was performed.
