Benign epithelial ovarian tumors

Two hundred and twelve patients with benign epithelial ovarian tumors managed consecutively at Hacettepe University Hospital between 1974-1994 were analyzed retrospectively. Benign epithelial tumors constituted 9.5% (212/2216) of all ovarian tumors and 28.5% (212/743) of the primary epithelial ovarian tumors during the study period. Of the patients with benign epithelial tumors, 104 (49.0%) had serous, 94 (44.3%) had mucinous and the remaining 14 (6.7%) had Brenner tumors. The surgical procedures varied from cystectomy to total abdominal hysterectomy according to the age of the patient. Bilaterality was encountered in 12.8% of serous and 10.6% of mucinous tumors. Ovarian carcinoma occurred synchronously in two patients. In two patients, serous cystadenoma was detected in the preserved ovaries following 3 and 7 years of initial conservative surgery, respectively. Serous tumors were relatively more common constituting approximately one half of the cases. Most of the patients presented with an abdomino-pelvic mass.
