Sketchy Path: Reproductive & GU - "Cervical Neoplasia" Flashcards
The endocervix is lined with _____________, while the ectocervix is lined with _____________.
columnar cells (like the columnar caterpillars); squamous cells (like the flat butterflies)
____________ are common benign findings in middle-aged women, arising from the os.
Endocervical polyps (like the caterpillar arising form the apple at the os stairs)
What bacteria are responsible for the pH of the vagina?
Lactobacillus, a Gram-positive rod (represented by the white flower with blue stamens)
The low pH is what stimulates metaplasia from columnar to squamous epithelium (like the “metamorphosis” transformation zone).
The most prevalent strains of HPV that cause CIN are ___________.
16 and 18 (like the girl with the car keys –16 –and the “I voted” sticker –18)
Which two proteins knock out tumor suppressors in HPV and CIN?
- E6: p53 (like the checkpoint 6 being broken by the 53rd runner)
- E7: RB (like the 7 in the Root Beer)
Other than HPV, what things increase the risk of CIN?
- Immunosuppression (guy on crutches)
- Multiple sexual partners (couple kissing)
- Smoking (kid smoking)
HPV has a special affinity for _____________.
the transformation zone where immature squamous cells develop (like the pill bugs on the transition zone)
The characteristic cell of HPV infection is ______________.
koilocytes (like the koi pond)
What do koilocytes look like?
Large vacuolated cytoplasms (like the eyes of the fish)
The stages of CIN go from ______________.
1 to 3 based on the layer from superficial to deep (like the butterflies piling up from deep to superficial)
Cervical cancer develops when what happens pathologically?
Dysplastic cells breaking through the basement membrane (like the cracks in the tank)
CIN I is also called _____________.
LSIL (like the Low fILter over the CIN I area)
CIN II and III are also called ________________.
HSIL (like the High fILter over the right areas)
Colposcopy is recommended for which stages?
All CINs
What percent of cervical cancer is SCC versus adenocarcinoma?
80:20 SCC:AC
