Q

Q

What is the histology for carcinoma in situ?

A

Both still have koilocytes
CIN I: lower 1/3rd dysplasia
CIN II: lower 2/3rd dyplasia
CIN III: dysplasia throughout without koilocytes but BM in tact – this is actually carcinoma in situ
–note on cytology II and III are group together as HSIL and I is LSIL

Q

What are the complications for invasive cervical cancer?

A

Most common cause of death is renal failure as a result of bilateral hydronephrosis as a result of invasion of the bladder
Constipation from rectal invasion
Invasion of vagina

Q

What does a pap cytology show?

A

Naturally in the cervix, squamous cells mature from bottom to top as they accumulate glycogen

  • -Smaller Nucleus: most mature/largest = superficial cells (pap smear)
  • Biggest nucleus/mitotically active = least mature = parabasal cells

Q

What is the P16 stain in regards to cervical cancer ?

A

if completely negative than not CIN

–marker of staining for high risk HPV

18
Q

Moving on to the low risk HPV strains 6 and 11. What are features? what do they cause?

A

No dysplasia: due to lack of insertion into the host genome

–raised painless warts around the vagina called Condyloma acuminatum

19
Q

What are the gross and histology features, slide 8, of Condyloma Acuminatum?

A

Gential Warts: cauliflower shaped that is raised, dry and scaly
Histology: Koilocytes with epidermal hyperplasia and hyperkeratosis (thickening of the stratum corneum) and parakeratosis (Stratum spinosum). no dysplasia (acathosis)

20
Q

What are symptoms of Condyloma Acuminatum?

A

Itching and burning of the vulva but no vaginal discharge and no pain

21
Q

What is used to visualize the warts in Condyloma Acuminatum?

A

Acetic Acid

22
Q

What are the complications of Condyloma Acuminatum?

A

No chance of malignant transformation

–papillomas in the larynx (benign) if baby comes through the birth canal

23
Q

Finally genital herpes is caused by which HSV strains?

A

HSV2 mainly but can be caused by HSV1 (oral sex)

  • -latent in the sacral nerve ganglion
  • -primary infection is worse than the reactivation
24
Q

What is the main mode of transmission of genital herpes?

A

Genital Fluids

–sexually and vertically transmitted (placenta or vaginal birth)

25
Q

Why is vaginal birth contraindicated in patients with genital herpes?

A

Baby get conjunctivitis and temporal lobe encephalitis so must do a C -section

26
Q

What is the presentation for patients with genital herpes?

A

Initial painful filled vesicles that ruptures to become ulcers in the vulvar region
–can become latent in sacral neurons and reactivate when stressed

27
Q

What is seen on Tzank smear for patients with genital herpes?

A

Intracellular cowdry type A bodies and multinucleated syncytial giant cells
–note PCR most accurate (b/c this is a virus)
can also do serology for IgG and IgM

28
Q

What are complications of genital herpes?

A
Immunocompetent = pain 
Immunocompromised = temporal lobe encephalitis and in babies vertical transmission
29
Q

What are the three M’s for any herpes?

A

Multinucleation
Margination of the chromatin pushed to the periphery
Molding of the cells

30
Q

The next vaginal issue to be discussed are Gartner’s Duct Cysts. What are some general features?

A
Benign 
Remnants of mesonephric ducts 
Anterolateral wall of vagina 
1-2cm
Mimics carcinoma clinically
31
Q

Next is vaginal adenosis, what are some features?

A

Seen in young girls (10yrs) whose mother got diethyl stilbesterol (DES) during pregnancy to prevent abortion

32
Q

What are histological features of vaginal adenosis?

A

Cells forming endocervical glands in vaginal wall

  • -may progress to clear cell adenocarcinoma years later
  • -benign and clinically mimics carcinoma
33
Q

Next is Sarcoma Botryoides (Embryonal Rhabdomyosarcoma). What are the features?

A

Girls less than 5 years old

  • –polypoid friable mass (bunch of grapes) hanging in the vagina
  • -highly malignant, malignant rhabdomyoblasts, cambium layer, fibromyxomatous stroma
34
Q

What is the histology for Sarcoma Botryoides?

A

Rhabdomyoblasts (precursors of skeletal muscle)

–requires surgery and chemotherapy

35
Q

Next is squamous carcinoma of the vagina, what are the features?

A

Primary is super rare

  • -usually due to a secondary cause of carcinoma from other parts of the female genital tract
  • -poor prognosis for either
  • -pelvic and inguinal nodes are based on location
36
Q

Finally the last topic of this card deck is Bartholinitis. What are the features?

A

Acute inflammation on inferior part of labium major – bartholin glands (which open into vaginal introitus)

37
Q

How does an abscess formation happen with Bartholinitis?

A

Blocking due to inflammation — abscess formation

  • -strep, staph, gonococci and e.coli
  • -drainage and marsupialization
38
Q

How do patients with Bartholinitis present?

A

Severe discomfort during intercourse

39
Q

How often should a women get a pap smear? what if it is abnormal?

A

once every 3 years if normal

and every 6 months if abnormal

40
Q

What are the two type of cervical cancer?

A

Endocervical (dysplastic glands)
Ectocervical (keratin pearls)
both HPV 16 and 18

41
Q

Besides cervical cancer, what other cancers can HPV 16 and 18 cause?

A

Anal
Penile
Vulva
Oral
