4. • Collection Procedure:
- Using standard paracentesis technique. A minimum of
10 mL of specimen is desirable for optimal cytologic
evaluation. Heparin may be added to the specimen to
reduce clotting.
- Place three (3) units of heparin per mL capacity of
the collection container. Gently agitate to thoroughly
mix the specimen and heparin.
- Always Submit the specimen along with the completed
cytology request form.
- The specimen should be refrigerated until transported to
the lab.

5. A pleural smear

6. Pericardial fluid

8. CSF is usually obtained through a lumbar puncture
(spinal tap).

10. • Gently strip the sub-areolar area and nipple with the thumb and
forefinger.
• Place the slide upon the nipple and draw it quickly across the
nipple. ***If 1 drop is obtained, get another slide and do the pull-
apart technique.
• Immediately immersed the slide into a bottle of 95% isopropyl
ROH or use spray fixative.
NIPPLE DISCHARGE
NIPPLE DISCHARGE

11. a. bronchial washing
b. bronchial lavage
c. bronchial brushing

12. - Bronchoscopically-directed brushing of identified lesion.
•Collection Procedure:
- Using standard bronchoscopy technique, identify the lesion in
question and obtain a brushing sample of the lesion.
- Gently apply the sample on to glass slide and immediately
immerse slide into 3% glacial acetic acid alcohol fixative.
- The brush tip should also be cut off into the solution.
Bronchial Brushings

13. Bronchial Washings
•Specimen:
Bronchscopically-obtained washing (preferable at least
10 mL) of the bronchi in the region of the suspected lesion.
•Collection Procedure:
-Using standard bronchoscopy technique, lavage the
distribution of the bronchus to be sampled.
-Collect the wash in a clean container. Label the
container with correct patient information and

14. NORMAL
-obtain at three consecutive morning
sputum specimens by deep cough
method.

Patient should fast overnight or for a minimum of six hours prior
to the procedure.
- Using standard endoscopy technique, lavage the area of
interest using a physiologic solution. Aspirate the solution and
place in a clean container.
- If transport of the specimen will be delayed more than four (4)
hours, the specimen should be refrigerated until transported to

CHANGES IN MALIGNANCY
CHANGES IN MALIGNANCY

33. Multinucleate cells
– with irregular hyperchromatic or bizarre nuclei should be suspicious,
Anisokaryosis
– considerable variation in nuclear size and shape is common in
malignant cells.
Giant single nucleus (polyploidy)
– often seen in malignant cells, polypoidic cells may also occur in benign
conditions, especially in thyroids of older women.

34. CYTOPLASMIC CHANGES
- cells of squamous carcinomas frequently show a tendency
to cytoplasmic eosinophila.
- adenocarcinoma cells may enclose, endometrial and
colonic cancers)
- cytoplasmic vacuolation is common in adenocarcinoma
cells, but may be also be seen in endometrial cells following
cutterage.

35. In general:
- malignant cells show reduced cohesiveness, possibly related to a
defect of the intercellular “zippers” i.e., desmosomes.
-Cancer cells are larger than their normal counterparts and
frequently show bizarre and grotesque shape.
Occasionally:
- exfoliated cells from epithelial tumors assume a greatly
elongated, fibrocyte-like appearance.

36. CELL PATTERN
•Examine for the small groups or clusters of cells
-Oblivious patterns
e.g. acini in adenocacinoma arising in glandular tissues
-Rosettes in neuroblastomas and ependymoma
-Stratification in squamous epithelial growths
-Whorls in mesotheliomas
If there are no patterns focus up and down the on cell
clumps
-In strips epithelium, irregular stratification of anisokaryotic,
hyperchromatic cells are helpful in diagnosing carcinoma of
cervix and bronchus.

37. OTHER CRITERIA
1. In bronchial secretion smear, abundant lymphocytes
are common in presence of malignancy, but may also
be found in certain inflammatory conditions and in
leukaemia.
2. The presence of old blood and blood pigments is a
minor indirect clue, but has many other etiologies.

38. VAGINAL CYTOLOGY
Vaginal cytology is a type of endocrine assay. Tracking changes in
the morphology of desquamated vaginal epithelial cells provides a
convenient means of assaying changes in estrogen levels.

39. •Vaginal smears may be taken regularly and often.
•Hormonal changes are best mirrored in the upper third of
the vagina.
•They can also be taken from the lateral walls because their
more accessible and less likely to be contaminated by
cellular debris or discharge.

41. -SUP{ERFICIAL CELLS

-Polyhedral flat cells
-Cytoplasm: may be acidophilic or
basophilic
-Presence of small dark pyknotic nuclei
(less than 6u)

42. Anucleate cells are abnormal which may be derived from:
1. smear contamination by the cells from the vulva
2. epidermization of the vagina or cervix resulting from
prolapse
3. leukoplakia of the cervix
4. ruptured membranes in pregnant women
5. marked hyper-estrinism

43. INTERMEDIATE CELLS

curl their edges.
- Expression of the combined estrogen-progesterone effect

menopause
-
-may also be found as a result of abnormal androgen stimulation,
either endogenous or exogenous

45. -PARABASAL CELLS

groups) and 1-4 days after the cessation
of the period (single)

clusters of small, oval dark cells;
Glandular cells: slightly larger.
-Nucleus: small and moderately dark
-Cytoplasm: basophilic and maybe
vacuolated

48. - “Lactobacillus acidophilus”
-Gram + slender rod bacteria
-

normal flora: establishes the low pH
that inhibits the growth of pathogens
-Stains pale blue to lavender
