H. Ferning Phenomenon
Histology of exfoliated, abraded, or desquamated cells
Cytology
This is the study or histology of the cells that are being removed from the bodv. Cells that was scraped from the body.
Cytology
• Study of cells directly taken from surfaces of excised specimens by touching them
Imprint/Abraded Cytology
Microscopic study of desquamated cells from epithelial surfaces
Exfoliative Cytology
Study of cells that have been shed or physically removed
Exfoliative Cytology
EXFOLIATIVE CYTOLOGY PURPOSES
• Assessing cancerous conditions (staging)
• Detection of asymptomatic cancers
• Asessment of female hormonal activity (sterilitv & endocrine disorders) - maturity index
• Determination of genetic sex - Barr bodies (conglomeration of chromatin, XX chromosome)
• Detect presence of possible infection
Material from fluids of the body may be examined either by:
Preparation of Smears
Preparation of Tissue Blocks (Cell Blocks)
Here are the examples of different body fluids that we might receive that might be subjected for exfoliative cytology:
Various Regions
• Vaginal Smear
• Endometrial and Endocervical Smear
• Prostatic and breast secretion
• Gastric or bronchial secretions
• Pleural or peritoneal fluids
• Sputum
• Smears of urine sediment
• Cerebrospinal fluid
SMEAR PREPARATION
• Make smears from fresh and moist material on clean slide; should not have_____
•________ is used to put identifiers on the smear (name, age, date, and type of smear);_______ may also be used.
• Immerse smears immediately in____ by a single uninterrupted motion (exfoliated cells decompose rapidly)
• Spray Fixatives:______
• Avoid_____ in the container to prevent the cells from being dislodged
• Optimal time:______ to allow dehydration, adhesion, and maximal penetration of the fixative
clumps
Diamond pen
frosted-end slides
fixative
12 inches or 1 foot away
vibrations
1 hour
• Best (yet flammable) fixative
The best fixative but it is flammable.
95% Ethanol-Ether
• Routinely used fixative
95% Ethanol
If smears cannot be made immediately, place the collected material in_______ (for all types of effusions) - replaced by_____
50% alcohol
Saccamono’s preservative
Saccamono’s preservative
50% Ethanol
2% Carbowax
Storage of sample:
add ROH and refrigerate
Storage of sample: Alcohol concentration
• 50% alcohol - pleural/peritoneal
• 70% alcohol - sputum
• 95% alcohol - urine, bronchial, gastric
Fixation of Mailed Specimen:
air-dry for 10-15 minutes after 2 hours of fixation and place it in a container
If specimen is more than a few drops:
• Centrifuge at 2,000 rpm for 2 minutes
• After centrifugation, decant the supernatant, and we will get a small portion of the sediment, then smear the sediment directly to glass slide, or cytocentrifuge directly on slide with albumin.
• Extra sediment can be used for cell block technique.
Viscous Specimen
Cervical, Vaginal, Prostate Secretion
Mucoid Specimens
Sputum
Bronchial
Stomach secretions
Watery Specimens
Urine, Exudate, Aspirate
General processing
Viscous Specimen
Cervical, Vaginal, Prostate Secretion
Immerse in ROH ASAP
General processing
Mucoid Specimens
• Sputum, Bronchial and Stomach Secretions
Dry smear edges before fixing (to avoid runoff)
General processing
Blood Srecimens
RBC can be destroyed by adding___________ of the specimen
2-5 mL of concentrated
Acetic Acid per 100 mL
General processing
Watery Specimens
• Urine, Exudate, Aspirate
Specimen is______ first and the sediment is smeared in an _______ glass slide.
In the event that there is excess sediment, it may be subjected to biopsy.
centrifuged
albumin-coated
• For adequate adhesion of smeared material.
ADHESION
• ADHESION
not recommended because it will retain the OG (Orange Green) of Pap stain.
Albumin
