frozen sectionCryostat section, 'frozen,' quick section Surgical pathology A rapid diagnostic procedure performed on tissue obtained intra-operatively, which is frozen in a synthetic material–eg, OCT–Miles Labs, sectioned with a cryostat, stained with H&E and viewed with a LM, allowing a rapid diagnosis of a pathologic tissue; a FS provides a surgeon with information necessary to guide therapy, and to determine the extent of further surgery at the time of surgical procedure
1. Differentiate between benign and malignant

4. Determine adequacy of tissue for further studies after the Pt is closed
5. Determine type of tissue, eg differentiate lymphoid tissue from parathyroid gland
