What is touch imprint?

Touch imprint cytology (TIC) is a well known pathological technique, which is used to provide a rapid intraoperative diagnosis of the biopsied tissue. Used as an adjunct to frozen sections, the procedure involves taking ‘touch’ imprints of the sample on a glass slide, fixing with alcohol and staining with H&E stain.
