Introduction: The frozen section is a quick way of histopathological evaluation of tissue fragments during the intraoperative period, being an important tool to help the surgeon in decision making. Objective: To assess the diagnostic accuracy of frozen section exams in different anatomical sites performed in the pathology service of a university hospital. Material and methods: Study of an exploratory nature, with a documentary-type quantitative approach. The sample comprises 803 medical reports of the freezing and definitive paraffin exams from January 1, 2015 to January 1, 2020, available at the Pathological Anatomy Laboratory of the Professor Alberto Antunes University Hospital (HUPAA), excluding 106 reports with data that has been unavailable for whatever reason. Results: It was observed that, of the 697 surgical specimens that make up this research, 540 (77.47%) were indicated for the diagnosis of the lesion and 157 (22.53%) for the assessment of margins. The most analyzed anatomical sites were the breast in 177 cases, lymph node in 120 and skin in 106 cases. Regarding the highest number of discordant results, globally, the breast comes first with 08 cases, followed by the ovary and annexes with 05 cases and, in relation to specific sites, the peritoneum presented 10.00% of its cases, while ovary and annexes 08.47%. The anatomopathological examinations by freezing presented a rate referring to the total accuracy of 91.10%, with the breast, specifically, 94.93%, intra-abdominal 93.75% and lymph node 93.33%. Conclusion: The observed accuracy rate is high and the numbers are in line with several similar studies, which reinforces the importance of the test and the quality of the procedures performed by the service in question.
