Caseous necrosis and liquefactive necrosis
admin | Nov 30, 2009 | 4 comments
During Pathology class …professor gave a lecture about difference between caseous necrosis (cheesy necrosis) and liquefactive necrosis .He teaches that both have lost there cell architecture and cytoplasmic content. And during microscopic examination both seem white in color. and I asked him how to differentiated both in microscopic Examination. He told that caseous necrosis have remaining debris so seen slightly red and liquefactive necrosis dose not have any debris so Stain white and liquefactive also contains a lot neutrophil. But when I observed in microscope I didn’t find any difference so any body know ,About this, how to difference between them.

well dost that’s a good curiosity but i am not clear whether you are asking about the gross or microscopic difference…the casous cheesy which we basically see in tuberculosis, cannot be stained with gram’s stain(both being acidic), that’s pink, so we stain it with prussian blue and see blue..i don’t how you saw pink. and liquefactive necrosis as you said is clear that should be seen white with lots of neutrophils..
i hope i made sense as slightly disturbed sense can be nonsense or missense
Thank u very much .I m talking about the microscopic examination especially histological section from a biopsy and staining with ZE.in that section both necrotic part is white in color.
i believe you have already found out the answer. if not you have the great opportunity of doing it yourself, do it, find it out and plz post it so that i can know it as well.
kocis…nice work…
i think comment made by bikash seems to be more logical….
