THINGS TO DO TO PREVENT PRE-CANCERS IN PAP SMEARS



Prevention of pre-cancers 

1. Avoid being exposed to HPV
2. Don't smoke
3. Get vaccinated

CELLULAR CHANGES ASSOCIATED WITH HUMAN PAPILLOMAVIRUS

Cytomorphological Criteria:
Cellular changes is caused by oncogenic type of HPV that is commonly from group 16 and 11.
The changes can be divided into 2 groups. Which are:
a) Classical Changes  (CC) – Cellular changes that occur as a confirmatory criteria of HPV infection
b) Non-classical Changes (NCC) - Cellular changes that occur at the early stage of the HPV infection. May be vary or have little differences from other cellular changes that caused by other viral infection.
Classical changes:
vKoilocytes – 60 – 70% cases
vKoilocytes is the term used to classified the cell that has perinuclear halos.
vIn HPV infection, the infected squamous cells will be seen having cytoplasmic condensation at the periphery giving hallow central portion.
Non-Classical Changes:
vKoilocytes are hardly be seen. 30 – 20% cases
vSquamous epithelial cell will appear to have heterogenous cytoplasm , unevenly stained. Mimicking dried smear.
vNuclei is small and pyknotic- slightly eccentrically placed
vNuclei varies from single to bitinucleated due to cytopathic effect.

vHyperchromatic nucleus with enlargement and eccentrically placed with slight, almost insignificant halos.



In the figure above, both are from the CP Pap-smear that shows characteristics of the infection due to HPV. In diagram “a”, the cytoplasm has shown irregularity of the outline. Besides, the heterogenousity of the nucleus is seen in variety in shapes and colours. Meanwhile in diagram “b”, the hyperchromatic nucleus is significantly clear with coarse chromatin. There is also binucleation occur one of the infected cells marked with “#”.

CELLULAR CHANGES CONSISTENT WITH HERPES SIMPLEX VIRUS

Cytomorphological criteria (Cellular changes) :
§ Nuclei have  a “ ground glass” appearance due to intranuclear viral particles.§ Enhancement of nuclear envelope caused by peripheral margination of chromatin. (Crowdy type A inclusion which contains virion push host chromatin to the periphery).§Dense eosinophilic intranuclear inclusions surrounded by a halo are variably present.§Large multinucleated epithelial cells with molded nuclei are characteristic but not always be present; mononucleate cells with nuclear features described above may be the only finding.§ ‘3M’ for nuclear infected with Herpes : Margination of nuclei, molding and multinucleation.§Sometimes necrotic epithelial cells are seen in Pap smear with HSV infection.


The figure shows multinucleate giant cells with ground glass appearance of the nuclei and margination of the chromatin. Molding of the nuclei is a characteristic feature of herpes infected multinucleate cells.

BACTERIA MORPHOLOGICALLY CONSISTENT WITH ACTINOMYCES





Actinomyces-like organism are identified cytologically as ball-like clusters of bacteria which have radiating filaments. These filaments can sometimes have a central core. Care should be taken when reporting actinomyces as other bacterial types appear very similar

Organism :
§Tangled clump of filamentous organisms, often with acute angle branching, are recognizable as ‘cotton-ball’ clusters.§Filaments sometimes have a radial distribution or have an irregular ‘wooly body’ appearance.§ Also known as “Gupta bodies”.§ Associated with Intrauterine device (IUD).
Cellular changes and slides background :
§ Inflammatory perinuclear halo may be seen.
§Masses of leukocytes adherent to microcolonies of the organisms, with swollen filaments or ‘clubs’ at the periphery.
§ Neutrophils often present.

CELLULAR CHANGES ASSOCIATED WITH BACTERIAL VAGINOSIS










Figure 5 : The figures show a) Cellular changes of squamous cell with small perinuclear halo is apparent associated with bacterial vaginosis and filmy background of slide are seen.  Inflammatory response is apparent.  . b) Squamous cells are covered with coccobacilli, they accumulate on the surface of large squamous cell to produce the so called “clue cells. However, the background is clean.

CELLULAR CHANGES ASSOCIATED WITH CANDIDA SPP


Candida can be seen in a cervical sample as segmented hyphae and spores. The hyphae often protrude from groups of squamous cells or they can be seen as kebabs. This is where the hyphae skewer groups of vertically aligned squamous cells.



Figure 4 : shows the skewered of the squamous cell,”shish-kebab” appearance. The pseudohyphae appears to be pinkish-purple.  There is one cell that shows the nucleoli in the nucleus clearly.  There are also the cells that has been recognized to be having pseudokeratinization.


Figure 5 : The figure above shows fungal organism morphologically consistent with Candida glabrata. Candida glabrata consists of small, uniform, round budding yeast forms surrounded by clear halo on Papanicolaou stain. Unlike other Candida species, it does not form pseudohyphae in vivo or in culture
