Traditionally we regard nuclear bubbling as incomplete fixation however I'm not
so sure that nuclear bubbling can't be caused by additional processing
problems. This morning I have some GI biopsies that fixed for nearly 18 hrs
that have a large amount of nuclear bubbling. We run the
Happy Friday Histoland,
I am looking for a qualified Histotech to fill a 2nd Shift Histology Supervisor
role in North Carolina. Please contact me for more details. Looking for a Tech
who is experienced in grossing and has some supervisory/lead/senior experience.
Please reach out to me for more
Can anyone share with me any worksheets you use to evaluate new trainees.
Embedding, cutting, special staining things like that. How you set target
goals?
Thanks in advance, Happy Friday.

We use hair wrapping paper used for perms. It is the same paper called "biopsy
wraps," but at a significant price reduction. You can buy a variety of sizes
and the wraps do not cause artifacts and are porous enough for ample solution
penetration. Biopsy paper comes in blue and other colors, but
Hello all,
I was wondering what everyone uses to secure biopsy and scant tissues
through processing. Also what would you recommend placing breast cores in
for processing. Having an argument with grossing staff and pathologist
about whether to use sponges, tissue paper, or something else. Looking
"Nuclear bubbling", manifested as round unstained areas in the nucleus, is
caused by incomplete dehydration of the section before staining. There is a
review on the subject that I cannot find at this moment.René

Sponges are available in different qualities. We use very soft ones, that
don't hurt the tissue.
I know, there are also very hard materials on the market, that may render
holes in the underfixed biopsies.

I've read about a group, that observed living cells during the
fixation-process. They saw bubbling in the first period of contact and
penetration of formaldehyde. After a certain time the bubbles disappeared
again.
Along this observation for me bubbles are a sign of too short fixation.

Hi James,
Nuclear bubbling artifact is most commonly seen in formalin fixed epithelial
cells, and GI biopsies are among those samples that are particularly
susceptible to it. It has been linked to inadequate fixation and also to
heating of slides prior to staining without complete air-drying
Histoscreen cassettes will work as well. Generally the cassette options are
expensive and may not work in all cassette printers, if you are using one.

Ultimately, get samples of whatever you like to
I really like this type:

from their website)
They are great for both large tissues, and also biopsies. A
Not advertising but I do a lot of research on tiny pieces of tissue and have
found the perfect cassette from Cancer Diagnostics. It is the Vortex
corner-less ones seen here.
WE use the biopsy sponges, THOROUGHLY soaked in formalin. They are easy to use
and not time consuming either for the grosser or the histologist. About 98% of
our volume is prostate biopsies, and we do not see the compression artifact

LOL, we used cigarette paper worked fine.
Now we use screen cassettes or HistoGel processing if super tiny.

Sponges can cause a compression artifact leaving some sort of "imprint" on the
surface of the biopsy, especially kidney and prostate Bx.I my experience tissue
paper is the best option. If you are having difficulties with the wrapping, you
can use "tea bags".René

Good afternoon,
Can someone touch base with me regarding the clearance angle of the microtome
blade? How would you describe a blade clearance angle that is too great or too
slight, and what microtomy problems are you likely to see with each? There
seems to be conflicting information out there
