Q

histologic changes (always talking about a biopsy) described with the following term

A

cervical intraepithelial neoplasia (CIN)- this term CIN has 3 degrees of severity (grades 1 through 3, the higher the number the more serious the neoplastic changes are)

Q

CIN 1 is

A

a low grade lesion, refers to MILDLY atypical cellular changes in the lower third of the epithelium. HPV cytopathic effect ( koilocytotic atypia) is often present

Q

CIN 2 is

A

considered a high- grade lesion, refers to MODERATELY atypical cellular changes confined to the basal 2/3s of the epithelium (formally called moderate dysplasia) with preservation of epithelial maturation. There is considerable variability in this category

17
Q

CIN 2 is stratified according to p16 immunostaining to identify precancerous lesion but

A

it has poor reproducibility and is likely a heterogeneous mix that includes lesions that could be called CIN 1 or 3.

18
Q

specimens that are p16- negative are referred to are referred to as

A

LSIL

19
Q

specimens that are p16- positive are referred to as

A

HSIL

20
Q

CIN 3 is a ??

A

high- grade lesion, refers to SEVERELY atypical cellular changes encompassing GREATER than 2/3rds the epithelial thickness and includes full thickness lesions (previous terms were severe dysplasia or carcinoma in situ) referred to as HSIL

21
Q

this is?

A

mild dysplasia, CIN 1

22
Q

this is?

A

moderate dysplasia, CIN 2, p16 staining should be performed

23
Q

this is?

A

severe dysplasia, CIN 3

24
Q

this is?

A

Carcinoma in situ, CIN 3

25
Q

changes in Bethesda guidelines

A

LSIL cervical cytologic specimens that contain a few cells that are suspicious but not diagnostic of HSIL are reported as atypical squamous cells and cannot exclude high- grade squamous intraepithelial lesion (previosuly there was no recommendation on how to report these)

26
Q

another change in Bethesda guidelines

A

benign- appearing endometrial cells are reported only in women 45 years and older. (old threshold was 40 years old)

27
Q

factors that may interfere with Pap

A

meds that alter results- digitalis and tetracylcine

vaginal meds/ contraceptives within 48 hrs of exam

use of lub on speculum

douching or tub baths within past 24 hrs

poor collection or fixation technique

28
Q

contraindication for pap

A

menstruation

29
Q

related test to pap

A

colposcopy- main role is to locate abnormal appearing epithelium and to dorect biopsies to areas in which cervical intraepithelial neoplasia (CIN) 2,3 or invasive ca is suspected

30
Q

what is transformation zone

A

defined colposcopically as the area bordered laterally by the original squamocolumbnar junction and medially by the new sqiamocolumnar junction. Photo is showing: The original or native squamocolumnar junction (SCJ) migrates onto the portio as the result of changes in the hormonal milieu or of vaginal deliveries

31
Q

teaching point- ASC-US

A

atypical squamous cells with uncertain significance- some cells not normal, but we don’t know why they changed or what impact they may have, usually not serious and may be d/t a vaginal infection or HPV, usually want a f/u exam repeat Pap or HPV testing

32
Q

teaching point- ACS-H

A

atypical squamous cells- high- some cells are not normal and there is a small possibility that they may be pre cancerous, we will perform a colposcopy to better look at cervix

33
Q

teaching point- AGC

A

atypical glandular cells- glandular cells produce mucus and are located in cervix or utuerus, these results mean some glandular cells are not normal but etiology is unclear. these changes are usually more serious, women with AGC have higher risk of cervical cancer, colposcopy recommended to examine any irregular tissue

34
Q

teaching point- LSIL

A

low grade squamous intraepithelial lesion- low grade means there are early changes in teh size/ shape of cells. often associated with presence of HPV, which may also cause genital warts. colpocopy, HPV testing recommended, or repeat pap

35
Q

teaching point- HSIL

A

high- grade squamous intraepithelial lesion- high grade means cells are very different from normal cells, usually precancerous and are more likely to lead to cervical cancer. colposcopy recommended to determine cancer risk

36
Q

teaching point- inflammation

A

if inflammation is present in the cells on the pap, it means that some WBCs were seen, its very common and usually does not signify a problem. if the inlammation is severe, we want to figure out the cause there may be an infection, we may want a repeat pap to see if the inflamation has improved

37
Q

teaching point- hyperkeratosis

A

this is a finding of dried skin cells on the pap. this change often occurs from using a cervical cap or diaphragm or from having a cervical infection. this rarely needs any more evaluation than a repeat pap in 6 mos- 1 year. if its still present we may want another pap or a colposcopy
