title: [The number and histopathologic type of ovarian tumors operated during cesarean section at the Polish Mother's Health Institute between 1990-2000].
abstract: OBJECTIVE
  The differences exist in concerning the estimation of number and histopathological type of ovarian tumors in pregnancy.
  
  
  METHODS
  From all 41,661 labours which took place in our Institute between 1990-2000 retrospective analysis of medical documentation of 11,050 caesarean sections (CS) as well as histopathological protocols were performed.
  
  
  RESULTS
  The prevalence of ovarian tumors removed during CS performed between 28-41 weeks of gestation was 0.19%. The prevalence of malignancy was low (0.005% of all labours). Unilateral cystectomy was found to be the most frequent kind of surgery and adult teratoma, serous cyst and paraovarian cyst as most common histopathological tumor types.
  
  
  CONCLUSIONS
  We conclude that ovarian tumors, especially of malignant type are rarely the complication of pregnancy. The most are benign, small, unilocular and smooth-wall cystic tumors.
