title: [The incidence of ovarian tumors in the third trimester of pregnancy].
abstract: RESULTS
  Between 1993 and 2000, 7529 patients underwent cesarean section (24.3% of 31,798 delivering women) at University Hospital in Poznań. There were 52 cases of simultaneous adnexal surgery among them because of ovarian tumors (1 case/144 abdominal deliveries; 1 case/612 pregnancies). In 43 cases tumor was accidentally diagnosed at time of operative delivery (1/174 abdominal deliveries). The average age of all delivering women was 27 +/- 7 yrs, among abdominally delivering 28 +/- 7 yrs. The respective value for patients with ovarian tumor was significantly higher--30 +/- 7 yrs. The mean diameter of the tumor was 4.8 +/- 4.7 cm, but the largest 30 cm. In 9 cases adnexectomy was performed, remaining patients were treated conservatively. Benign cyst teratoma was diagnosed in 26.9%, cystis simplex in 21.2%, fibroma in 15.4%, endometriosis and luteal cyst every in 9.6%. There were two cases of malignant tumors, both diagnosed earlier: dysgerminoma and adenocarcinoma.
  
  
  CONCLUSIONS
  1. incidence of ovarian tumors of pregnant women was previously probably underestimated, 2. the risk of malignant ovarian tumor is relatively low.
