Lecture 7 - Cervical Disorders Flashcards
Transitional area
endocervix –> endometrium
Endocervix
canal portion of cervix
columnar epithelium
Ectocervix
protrudes into vagina
nonkeratinizing squamous epithelium
How long is the cervix?
2-4cm
What is happening to the cervix during menarche?
acidification –> ectocervix undergoes squamous transformation –> metaplastic change radiates inward from original squamocolumnar junction to new SCJ –> creates transfomration zone
Ectropion
seen during periods of higher estrogen like during puberty or OCPs
this is a normal and benign variant to the cervix
Nabothian cysts
a normal benign variant of the cervix
form during squamous metaplasia –mucus trapping
we don’t treat these –they might pop on their own but might come back
Cervical polyps
MC benign cervical neoplasma
hyperplastic endocervical folds of columnar epithelium
pts complain of postcoital bleeding –> this is why we typically remove them
however if the pt presents with these post menopausal we excise and biopsy
Cervical insufficiency
aka incompetence
painless premature dilation (the fact that it is painless sets it apart from preterm labor)
intrinsic or acquired (commonly from prior surgical procedures)
pregnancy loss or preterm delivery
Cervical stenosis
rare
acquired scarring of the cervical canal in response to trauma or hypoestrogenism
we typically don’t know about the stenosis until time for dilation in labor, it either wont dilate or it will dilate slowly and then all at once (like it popped)
What is the most common STI?
HPV
strongest risk factor = number of sexual partners
15 strains are high risk
squamous cell (rarely adenocarcinoma) –slow growing
Why don’t we start screening for HPV until 30s?
because we assume that everyone in their 20s having sex has HPV, but they are clearing these infections
once they get older they’re unable to clear these infections and thus can lead to worse effects
What are the current pap smear guidelines?
start at 21 (regardless of when pt first had sex)
every 3 years until 29
add HPV co-testing at 30, every 5 years until 64
discontinue after 65 if negative screening in past 10 years
What are the exceptions to the pap smear guidelines?
for people who have HIV
if they were born with it they have to get a pap smear every year starting when they have sex
if they acquired it they have to get it at time of dx and every eyar following
Colposcopy
microscope on wheels to look at cervix
acetic acid or Lugol’s stain to identify abnormal cells that need to be biopsied post abnormal pap smear results
