Özet

Ovarian epithelial tumors are one of most frequently encountered gynecological specimens

sent to pathology laboratories intraoperatively.Preoperative diagnosis of an ovarian mass is

limited due to low sensitivity and specificity imaging studies,serum markers.Therefore,

intraoperative frozen section evaluation, oophorectomy or limited surgical staging for

borderline tumors in younger patients is crucial to preserve necessary surgical scope, ie

fertility or to determine comprehensive staging procedure for ovarian carcinomas.

Our aim in this study is to present rate of agreement between definite histopathological

results of sections obtained by intraoperative examination and postoperative paraffinization in

cases diagnosed with borderline ovarian tumor,undergoing oophorectomy for 4.5 years in our

department.Reports of cases with ovarian mass, clinical-radiologically suspected malignancy,

and intraoperative examination requested between May 2017 and December 2021 were

reviewed retrospectively.A total of 80 patients with ovarian mass were diagnosed with

borderline tumor in our department.There were 52 patients who underwent intraoperative

examination.The mean tumor diameter was 11.3 cm. 45 patients were correctly diagnosed

under frozen conditions.The sensitivity of intraoperative examination in predicting

malignancy was calculated as 86.5%. 71.4% of those who were misdiagnosed were cases

with borderline mucinous tumors.A large number of samples were taken from post-frozen

materials and paraffinized sections were examined.53.8% of these neoplasms were diagnosed

as borderline serous tumor, 8.9% of borderline mucinous tumor, 11.5% of them as borderline

seromucinous tumor,5.8% of them as borderline endometrioid tumor.Although intraoperative

frozen section diagnosis seems to be an accurate technique for histopathological diagnosis of

ovarian tumors,frozen section evaluation of ovarian borderline tumors continues to pose an

important diagnostic challenge for pathologists.Large-diameter tissues, particularly mucinous

subtype, are limitations to use of frozen sections.Regular reassessment or consultation

regarding disagreements between frozen section diagnosis and final permanent paraffin

diagnosis can be undertaken by both surgeons and pathologists to determine the most

appropriate intraoperative management for patients with ovarian tumors.
