Objective: To measure the accuracy of the frozen section in the diagnosis of malignant adnexal masses. Methods: 192 patients who had been operated due to adnexal masses and submitted for intraoperative frozen section were evaluated retrospectively. The results were compared with paraffin section. Results: In all cases, opinion on frozen section was available. The sensitivity of frozen section through benign, borderline and malignant tumors were 98.8%, 90% and 93.8% respectively, where as the specificity of the latter tumors were 92.3%, 98.9% and 100% respectively. The overall accuracy was 97.9%. Two benign cases were diagnosed as borderline, one borderline as benign and one malignant case as a benign in frozen section. The misdiagnosed malignant case was mucinous and the others were serous type tumors. Conclusion: Frozen section has high accuracy in the diagnosis of malignant ovarian tumors. Paraffin section is the gold standard method, but because of the need for the quick result in the operation for the surgical management, frozen section must be performed to all suspicious adnexal masses.
