Frozen section technique is a valuable tool used to rapidly prepare slides from tissue for microscopic
interpretation, in surgical pathology; frozen sections are routinely used for rapid intra-operative diagnosis,
providing guidance for the surgeons. An audit of this vital procedure helps to identify the efficiency,
diagnostic error rates, and cause of the error and also preventive measures which can be taken to avoid
those errors. Ours was a retrospective study undertaken at Saveetha medical college, Chennai. In our study
out of the 160 cases, 154 cases were concordant with the final histopathological diagnosis and 6 cases were
discordant, which gives an accuracy rate of 96% and a discordance rate of 4%. Discordance was primarily
due to interpretation errors and errors due to limited sampling during frozen section. Knowledge of the
pitfalls and causes of diagnostic errors are important in improving the accuracy of this process. Regular,
periodic audits will go a long way in addressing this issue.
