Tissue imprints in surgical pathology: a rapid intraoperative diagnostic aid.


We studied the intraoperative diagnostic value of imprint cytology in 230 samples obtained from surgical specimens submitted for frozen section diagnosis. A rapid hematoxylin-eosin stain was used. Intraoperative imprint cytology achieved an accuracy rate of 94.3%; for benign lesions the accuracy was 97.5%, and for malignant lesions it was 91%. Overall, the false-negative and suspicious-for-malignancy rates were 1.3% and 4.3%, respectively. No false-positive results were found. The diagnostic yield when intraoperative imprint cytology and frozen section were used together was 99%. It is apparent that imprint cytology is a quick and simple method with wide applicability in the histopathologic diagnosis of lesions from all organs. The value of the method is enhanced when it is used with frozen section diagnosis.
