The frozen section procedure as practiced today in medical laboratories is based on the description by Dr Louis B. Wilson in 1905. Wilson developed the technique from earlier reports at the request of Dr William Mayo, surgeon and one of the founders of the Mayo Clinic [3] Earlier reports by Dr Thomas S. Cullen at Johns Hopkins Hospital in Baltimore also involved frozen section, but only after ...
Modern frozen section method. Frozen section histology does not give the added margin of safety by the cytotoxic Mohs paste, [14] originally used by Mohs. This paste might have destroyed any residual cancer cells not detected by the pathologist. Missing epidermal margins. Ideally, the Mohs section should include 100% of the epidermal margin ...
Louis Blanchard Wilson (December 22, 1866 – October 5, 1943) [1] was an American pathologist and the chief of pathology at Mayo Clinic from 1905 to 1937. Wilson is most famous for initiating the routine use of the frozen section procedure for rapid intraoperative diagnosis.
The second method of histology processing is called frozen section processing. This is a highly technical scientific method performed by a trained histoscientist. In this method, the tissue is frozen and sliced thinly using a microtome mounted in a below-freezing refrigeration device called the cryostat. The thin frozen sections are mounted on ...
Frozen section procedure: water-rich tissues are hardened by freezing and cut in the frozen state with a freezing microtome or microtome-cryostat; sections are stained and examined with a light microscope. This technique is much faster than traditional histology (5 minutes vs 16 hours) and is used in conjunction with medical procedures to ...
Similar to the frozen section procedure employed in medicine, cryosectioning is a method to rapidly freeze, cut, and mount sections of tissue for histology. The tissue is usually sectioned on a cryostat or freezing microtome. [12] The frozen sections are mounted on a glass slide and may be stained to enhance the contrast between different tissues.
