This study was performed to compare the clinical characteristics of benign and malignant tumor in postmenopausal woman. METHODS: We reviewed the chart of 91 postmenopausal women over 50 years of age, operated and confirmed by postoperative histopathologic study at Department of Obstetrics and Gynecology, Soonchunhyang Chunan Hospital, from January 1st 1995 to December 31th 1998. RESULTS: Benign ovarian tumor was found in 85.7% (78 cases) and malignant ovarian tumor was found in 14.3% (13 cases). Age distribution of malignant ovarian tumors showed the highest frequency in the age group 61-65 years compared to benign ovarian tumor. In the larger than 10 cm in tumor size, there were 7 benign (58.3%) and 5 malignant (41.7%) lesion. There was no evidence of malignant tumor according to the parity. In malignant lesion, stage I was seen in 15.4%, stage II in 30.7%, stage III in 7.7%, stage IV in 23.0% and unexplored in 23.0%. Tumor marker of CA 125 in malignant lesion was increased in 69.2%. As the subjective symptoms of benign lesions, no symptom was noticed in 38.4%, but in malignant lesions, lower abdominal pain was noticed in 38.4% as the most common. Bilaterality in benign lesions was noted in 29.4% and the same in malignant lesions was 15.3%. CONCLUSIONS: Considering the above results, as the tumor size increases, the risk of malignancy increases.
