Distribution of 123 ovarian tumors: 73.2% (90) were benign, 7.3% (9) were borderline tumors and 19.5% (24) were malignant. 68 of the cases (55.3%) were surface epithelial-stromal tumor; 34 of the cases (27.7%) were germ cell tumors; 10 of the cases (8.1%) were sex cord-stromal tumors; one of the cases (0.8%) was vascular tumor and 10 of the cases (8.1%) were metastatic tumors.
