Female GU Path (Carpenter)- Leah : ) Flashcards
Normal cervical epithelium
ectocervix: stratified squamous
endocervix: columnar cells w/ mucin
(not true glands)
Appearance of normal:
endometrium?
myometrium?
endometrium: glands and stromal tissue
myometrium: thin SM cells w/ cigar like nuclei
Normal fallopian tube epithelium appearance?
ciliated/nonciliated columnar cells
+intercalated peg cells
HSV2: basic viral structure
DS DNA, linear
icosahedral, enveloped
Time course HSV genital infection?
Likelihood that HSV will be transmissed via sex?
In 1/3 patients who have intercourse w/ infected individuals:
lesions appear ~3-7 days later, heal ~ 1-3 weeks
can establish latent infection
Locations of HSV2 lesions?
Test (dx) of choice?
painful, red external lesions (vulva/vagina/cervix)
dx w/ PCR (pap not sensitive, Ab’s absent in acute phases-if present indicate reactivated latent infxn.)
Appearance of HSV cells on histo?
“ground glass nuclei”
-looks almost like soap bubbles or deer turds to me (Haha!)
Molluscum Contagiosum:
basic viral structure
Poxvirus, dsDNA
complex capsule, naked
cytoplasmic replication**
What are the types of molluscum contagiosum viruses?
How are they transmissed?
-Types 1-4, Type 1 most common, Type 2 on genitals
(similar to herpes- 1 common, 2 genital)
-Can be transmitted sexually, by skin contact, or by contact with contaminated surfaces (kids)
What do molluscum contagiosum infections look like grossly and on histo?
gross: dome shaped lesions w/ dimples
histo: intranuclear inclusions
Candida: for the boards, what is the structure of this fungus?
How does it look on wet prep?
Dimorphic
mold in the cold (pseudohyphae)
yeast in the heat (germ tubes)
Spaghetti and meatballs on wet prep
Prevalence of candida infections?
Risks for yeast infection (4)?
Sx and Dx?
Most common female GU infection
Risks: OCPs, pregnancy, diabetes, Abx
(Immunosuppression/ flora or pH disruption)
Sx: white cottage cheese discharge, itching
Dx: wet prep
Trichomonas:
What is the structure of this bug? How does it look on wet prep?
Protozoa w/ flagellum, may be motile on wet prep
Classic presentation of trichomonas infection? (3)
Risk assc with infection (2)?
Dx method?
- strawberry cervix; green/ yellow discharge; +whiff test
- ^^ HIV/ preterm delivery (thus low BW) risk
- Dx on wet prep
Gardnerella:
bacteria structure, prevalence in women?
- pleomorphic gram negative rod
- some evidence that it may be normal flora, 70% of those infected aren’t symptomatic.
Classic presentation of gardnerella?
White discharge, “clue cells”, (FA says +whiff/ fishy odor: FA knows best!!)
Chlamydia Trachomatis:
basic bacterial structure AND typical infections?
- atypical gram negative, intracellular (can’t make ATP!!!)
- “Higher” infections (cervicitis, endometritis, salpo-oophoritis, PID)
Chlaymida:
Dx?
Important Risk?
- can dx w/ PCR OR URINE!!
- INFERTILITY risk
Gonorrhea: basic bacterial structure
gram negative diplococcic, intracellular
see ‘coffee beans’ inside neutros on histo
PID: bugs causing disease (3)
- gonorrhea
- chlamydia
- enteric bacteria
- *Typically polymicrobial when peurperal (following normal delivery)
Cause of/ risks for PID?
Outcome of PID (4)?
Causes:
- Anything foreign going up inside of you.
Babies….. metal stuff in procedures… abortion.
Outcomes:
- suppurative salpingitis–> adhesions and infertility
- peritonitis
- bacteremia
- intestinal obstruction
What bugs are usually assc with post-partum PID?
polymicrobial!!
Gonococcal/Non-gonococcal PID: describe the course of disease (important difference?)
gonococcal: enters bartholin glands/cervix –> travels upward + spares endometrium (infects outer layers–mucosa + submucosa)
nongonococcal: lymphatic spread, infects ENDOmetrium + myometrium (DEEP infection)
- What are the two leukoplakias (white plaques) of the vulva?
- When does each occur?
- Key histo difference between the two?
- lichen sclerosis (post-men)–> Epi THINS
- lichen simplex chronicus (excess scratching)–> ACANTHOSIS (THICK Epi)
Lichen sclerosis: histo
Lichen simplex chronicus: histo
sclerosis: epi thins, dermal atrophy and scarring
(response to being an old fart!!)
chronicus: epi thickens, dermal inflammation and hyperkeratosis (response to irritation!!)
Condylomas: assc virus? Are they precancerous? Location of infection? Histo?
- HPV 6,11– not precancerous
- warts on outer genitals/ anus
- koilocytosis, “raisin like cells”
Vulvar intraepithelial neoplasm (VIN): two types? prognosis? average age? typical morphology?
Women over 60yoa
- (basically squamous carcinoma in situ; precursor lesion)
- HPV related vs. non-HPV
- good prognosis
HPV related VIN:
what does it look like grossly? on histo?
Age group?
-warty/ basaloid type/ koilocytes (exophytic lesion)–>
white plaques on vulva, vagina, uterus
-Patients are younger than in non-HPV type
Non-HPV VIN:
Whats it look like on histo/ grossly?
Who gets it?
- nodules, keratinization + invasive pattern
- OLDER women w/ long standing hyperplasia/ leukoplakia (lichin disorders) –> progresses to VIN
Malignant melanoma of vulva:
who gets it?
what might it be mistaken for?
prognosis?
- older adults
- poor prognosis because late detection
- mimics Pagets
What does Pagets disease of the vulva look like grossly? on histo?
Who gets it?
How does it compare to mammary Pagets?
- red crusted lesion; confined to epidermis, large halo cells
- occurs in post-meno. white women
- NOT asstd. with DEEPER cancer (remains in Epi)
- MAMMARY Pagets is 100% associated with DEEPER cancer
What type of cancer is extramammary pagets?
primary cutaneous adenocarcinoma
- Tumors come from apocrine ducts or keratinocytic stem cells
**She worded this really weird in her note packet, but after her lecture and pathoma I am pretty confident that this is disease is always considered a primary cutaneous adenocarcinoma that RARELY invades past the Epi and is thus RARELY associated with deeper malignancy (vs. the boobie one which is nearly 100% associated with deeper malignancy).
Vaginal Intraepithelial neoplasm (VAIN):
compare it to Vulvar IN
- vaginal is most always HPV assc (don’t get non HPV)
- most vulvar (VIN) are NOT HPV asstd.
- VAIN + VIN same otherwise (warty exophytic lesion, white plaque)
Vaginal Squamous cell carcinoma:
Where does it come from and how common is it?
- usually HPV assc carcinoma that spreads from the cervix
- 1-2% of cervical squamous cells spread to vagina
Adenocarcinoma of the vagina is assc with what drug?
The drug is more commonly assc with what condition?
- adenocarcinoma seen in young women whose mothers took DES (1%)
- more commonly these girls get VAGINAL ADENOSIS: red granular foci of squamous/ columnar cells, ^^glands
Tell me about embryonal rhabdyomyosarcoma of the vagina?
who gets it, what does it look like grossly/ histo, prognosis?
- kids under 5yoa
- grape like, protrudes from vagina
- has cambium layer, tad pole cells, rhabdoblasts
- good prognosis
How and where does squamous metaplasia of the cervix occur?
What is the consequence?
-menarche –> ^^ estrogen –> ^^ glycogen –> ^^ bacteria –> low pH –> endocervix gains squamous cells where it should have columnar
- normal process but cells are susceptible to HPV infection
- *get dat transition on pap, yo.**
Two “inflammatory” disorders of the cervix?
- cervic(itis) – duh
- endocervical polyps
How common is cervicitis? When is it a concern?
- most women get cervicitis, esp multiparous women
- usually benign but worry about gonorrhea, chlamydia, mycoplasma, HSV
Endocervical polp:
What does it look like?
What does it cause?
- mucopolypoid mass, may protrude from os
- causes bleeding –> rule out more dangerous causes
Who gets HPV? Is it worrisome? When do we test for it?
- Most women exposed by age 50, usually cleared by immune system –> only dangerous if infection persists
- Do not test in young people, only in 30+ or w/ abnormal pap at age 21+
Cause of nearly all cervical cancer?
What are three important risk factors for cervical cancer?
-Persistent HPV 16,18, 31, 33 infections
risks for persistence: OCPs, smoking, immunosuppression
HPV 18 + 45 are risks for?
endocervical adenocarcinoma
What cells become infected by HPV?
-INFECTS immature cells in squamocolumnar junction
(or immature anal cells in males)
-REPLICATES in mature cells, ie vagina
What does HPV look like in mature cells?
-koilocytes: clear halo, raisin nuclei
Describe the oncogenicity of HPV:
E6/7 proteins inactivate Rb/p53 tumor supressors
