Saemisch's section see under operation. serial section histologic sections made in consecutive order and so arranged for the purpose of microscopic examination.
frozen section Etymology: ME, fresen + L, sectio a histologic section of tissue that has been frozen by exposure to dry ice. frozen section a specimen of tissue that has been quick-frozen, cut by microtome, and stained immediately for rapid diagnosis of possible malignant lesions. A specimen processed in this manner is not satisfactory for detailed study of the cells, but it is valuable because it is quick and gives the surgeon immediate information regarding the malignancy of a piece of tissue.
frozen said of material kept at less than 0°C. Biological materials are frozen solid because of their high water content. frozen embryo see embryo transfer. frozen meat meat preserved at low temperatures in a freezer. frozen section a specimen of tissue that has been quick-frozen, cut by microtome, and stained immediately for rapid diagnosis of possible malignant lesions. A specimen processed in this manner is not satisfactory for detailed study of the cells, but it is valuable because it is quick and gives the surgeon immediate information regarding the malignancy of a piece of tissue. frozen semen see semen. section 1. an act of cutting. 2. a cut surface. 3. a segment or subdivision of an organ. abdominal section laparotomy; incision of the abdominal wall. cesarean section delivery of a fetus by incision through the abdominal wall and uterus; see also cesarean section. frontal section a section through the body passing at right angles to the median plane, dividing the body into dorsal and ventral parts. frozen section a specimen cut by microtome from tissue that has been frozen; see also frozen section. perineal section external urethrotomy. sagittal section a section through the body coinciding with the sagittal suture, thus dividing the body into right and left halves. serial s's histological sections of a specimen made in consecutive order and so arranged for the purpose of microscopic examination. trial section
the gradual transverse cutting of a tissue or structure, usually to ascertain its composition or to limit the incision to only one component, e.g. scar tissue surrounding a nerve. frozen section Cryostat 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
Frozen section–indications
1. Differentiate between benign and malignant
2. Determine type of malignancy–eg, lymphoma v. carcinoma
3. Evaluate tissue margins for involvement by malignancy, eg basal cell carcinomas
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
