This presentation is useful for understanding the role and application of the frozen section in histopathology. If trimmed too little, the section will not include some critical feature. If trimmed too much there will be unnecessary wastage of tissue and potential loss of some precious portion of the sample.

Frozen section is a pathology procedure that allows rapid microscopicexamination of a specimen during surgery. Sir Louis B. Wilson pioneered the technique in 1905 at the Mayo Clinic to enable urgent intraoperative diagnosis.

Frozen sectionisa pathology procedure that allows rapid microscopic examination of a specimen during surgery. Sir Louis B. Wilson pioneered the technique in 1905 at the Mayo Clinic to enable urgent intraoperative diagnosis. The procedure involves snap freezing tissue, sectioning it with a cryostat microtome, and staining for quick analysis.
15 CRYOSTAT AND FROZEN SECTION - The National Institute of ...
Cryostat: Cryostat is used in medicine to cut histological sections. They are usually used in a process called frozen section histology. The cryostat is essentially an ultrafine “deli-slicer”, called a microtome, placed in a freezer. The cryostat is usually a stationary upright freezer, with an external wheel for rotating the microtome.

Some key points include: - Frozen section allows rapid diagnosis of possible malignant lesions during surgery through quick freezing, cutting, and staining of tissue. - It provides advantages like allowing surgeons to obtain additional tissue samples if needed and ensure entire masses are removed.

Frozen sections allow rapid diagnosis and special staining techniques compared to fixed sections. Frozen sections can be prepared using either a cold knife procedure or cryostat procedure. The cryostat procedure uses a cryostat machine maintained at -18 to -20°C to freeze and section tissue.

Frozen sectionanalysis was found to have poor sensitivity in identifying adverse pathology (59.1%), which was improved in patients with preoperative CIS (68.0%). After a median (interquartile range) follow-up of 12.4 (1.9-10.1) years, 28 patients (1.4%) developed UTUC recurrence. There were no uretero-enteric anastomotic recurrences.
Frozen Section Technique I - Pathology Innovations
1) A section is cut leaving an attachment of medium at the top. 2) The wheel is turned in opposite direction bring the section back to the face of the block. 3) Section is retrieved by placing the slide over the tissue on the face of the block.
Frozen sections of tissue are prepared using a cryostat to quickly obtain thin sections for histological examination and diagnosis. A cryostat maintains tissue at freezing temperatures to allow sectioning without ice crystal formation.

The frozen section is therapidtissuesection by cooling the tissue with the help of cryostat to give an immediate report of the tissue sample. This is especially needed in a large hospital to diagnose the lesion or extent of the lesion at the time of operation.
