This article deals with stains. The H&E stain is only one of many stains that are used in pathology.
Non-H&E stains are often referred to as special stains.
Where to start...
Principles
When considering additional (i.e. special) stains one should (in order) do the following:[1]
- Make sure one has exhausted the clinical history; history is considered the best special stain.
- Special stains (below).
- Immunohistochemistry (dealt with in a separate article).
- Molecular testing, electron microscopy.
Common stains
- H&E stain.
- PAS stain.
- PAS-D stain.
- AFB stains, e.g. Ziehl-Neelsen stain.
- Congo red.
- GMS stain.
- Gram stain.
Immunohistochemistry
General
- Abbreviated IHC.
Interpretation
Simple version:
- Positive is (usually): brown.
- Negative tissue is: light blue.
Important notes:
- One has to know where the target (of the antibody) is supposed to be, i.e. cytoplasm vs. cell membrane.
- The edge of the tissue may have light staining - edge effect.
- If everything is brown... suspect that it didn't work.
- In some situations you're blessed with an internal control, e.g. in renal tumours CD10 will stain RCC and the proximal tubule, in GISTs - CD117 the mast cells are positive.
Work-up of infection
It often not possible to be definitive by staining.[2]
Basic panel:
- Gram stain - for bacteria.
- GMS stain - fungal stain.
- PAS (or PAS-D) - fungal stain.
Fungi
Fungi are a type of microorganisms. They are seen by pathologist every once in a while.
Specific stains
What follows is a big list... of stains.
Haematoxylin and eosin stain
- Abbreviated H&E.
Haematoxylin phyloxin saffron stain
General
- Abbreviated HPS.
- An alternative to the H&E stain - some pathol. departments use this as their standard.
Interpretation
- Haematoxylin = blue -- stains nucleus.
- Phyloxin = pink -- stains muscle and cytoplasm.
- Saffron = yellow -- stains collagen.
- An alternative to H&E stain.
- Fibrosis is easier to see on HPS than H&E... as one can see the collagen.
Images
Periodic acid Schiff stain
- Abbreviated PAS.
Primary application
- Kidney biopsies, medical.
- Liver biopsies, medical.
- Positive in alpha-1 antitrypsin deficiency.
Utility
- Stains - lipofuscin,[3] basement membranes, fungi, glycogen, (neutral) mucin.
Interpretation
- Magenta = glycogen, mucin, fungi.
- Blue = nuclei.
Ref.:[4]
Image
Periodic acid Schiff fungal stain
- Abbreviated PASF.
Primary application
- Look for fungal organisms.
Interpretation
- Light purple = fungi.
- Light green = background.
- Washed-out light purple = Gram positive bacilli.
Note:
- This is much improved over the PAS in the context of skin, as the background is similar to the fungal organisms.
Periodic acid Schiff with diastase
- Abbreviated: PAS-D and PASD.
General
Use
- Stains mucin.
- Used to identify glycogen (together with PAS stain).
- Glycogen = clear (digested) on PAS-D.
- Glycogen = magenta on PAS.
Notes: [6]
Interpretation
- Light purple = fungi.
- Light blue/pink = background. ???
Gomori methenamine-silver stain
- Abbreviated GMS.
Note:
- GMS is "Grocott's methenamine Silver" according to WMSP.[7]
Use
- Useful for fungi.
- Pneumocystis jirovecii - cause of pneumocystis pneumonia (PCP).
- Histoplasma - cause of histoplasmosis.
- Histoplasma = black, round balls.
Image
Acid-fast bacilli stains
- Abbreviated: AFB.
There are several AFB stains:
- Ziehl-Neelson stain - used to look for Mycobacterium tuberculosis.
- Fite stain - used to look for Mycobacterium leprae[8] and preferred stain for Mycobacterium avium complex.[9]
- Auramine-rhodamine stain.
Ziehl-Neelsen stain
- Most popular acid-fast bacilli stain.
- Stains other mycobacteria -- not specific for tuberculosis.
- Stains Nocardia.[10]
Image
Fite stain
Interpretation:
- Red = AFB.
- Blue = background.
Auramine-rhodamine stain
- Fluorescent stain.
Image
Kinyoun stain
- Another AFB stain[11] - useful for cryptosporidiosis and microsporidiosis.[12]
Congo red stain
Use
- Used to look for amyloid.
- Mnemonic: CRAP = congo red amyloid protein.
- An alternate stain for amyloid is Thioflavin T.
Note:
- Thick sections (~10 micrometers) are considered a requirement for the stain to work properly.[13]
- If the section is too thin... it doesn't work.
Interpretation
- Amyloid = pink/red.
- Nuclei = blue.
Ref.:[14]
Image
Congo red staining in cerebral amyloid angiopathy. (WC)
Thioflavin T stain
Use
- Used to look for amyloid.
Interpretation
- Amyloid = green.
Image: Amyloid (inano.au.dk).
Gram stain
Use
- "It is useless for finding bacteria."[15]
- If they are to be seen... they'll be visible on H&E.
Note:
- Microbiology is better at finding organisms than pathology.
