Vulva and Vagina pathology Flashcards
germ cells are from what
endoderm
urogenital ridge is from what
mesoderm
germ cells migrate to where
urogenital ridge to form ovary
what forms the uterus and upper vagina
mullerian ducts
all epi surfaces and lining share what origin
coelemic (mesothelium)
mesonephric/wolfian duct remnants
can create cysts gartner cysts- next to uterus sup to cervix can also form in mesovarium/broad ligament
didelphys
when mularian ducts do not fuse -> two uterus’, 2 vaginas different from bicornate bc bicornate only has one vagina slightly higer risk for 2-3rd trimester spontaneous abortions DO NO have higher rate of twins or PID
kelbsiella granulomatous
gram neg donovan body
gardnerella vaginalis
gram neg clue cells
N. gonorrhoeae
gram neg diplococcus
Treponema pallidum
syphilis spirochete
HPV
koilocyte if low grade koilocyte + nuclear enlargement if high grade
HSV
multinucleated giant cell with intranuclear homogenization and inclusion bodies
CMV
bulbous intranuclear inclusion body
molluscm contagiosum
molluscum body
Trichomonas vaginalis
trichomonad
Actinomyces isralii
causes PID sulphur granules
M. tuberculosis
necrotizing granulomas
C. albicans
candida sp
What infections can be seen in vulva
herpetic ulcers molluscum lesions HPV (genital warts, intraepi neoplasia, invasive carcinoma) N. gonorrhoeae (skene gland adenitis) Candida trichomonas
what infections can be seen in vagina
herpetic ulcers HPV (genital warts, intraepi neoplasia, invasive carcinoma) Gonorrhoeae (vaginitis in kids) candida trichomonas

herpectic ulcers HPV (genital warts, intraepi neoplasia, invasive carcinoma) Chlamydia (follicular cervicitis, endometritis, salpingo-oophoritis) Gonorrhoeae (vaginitis in kids) candida trichomonas gardnerella
what infections can be seen in corpus
Chlamydia (follicular cervicitis, endometritis, salpingo-oophoritis) Gonorrhoeae (vaginitis in kids)
what infections can be seen in adenxa
Chlamydia (follicular cervicitis, endometritis, salpingo-oophoritis) Gonorrhoeae (vaginitis in kids)
Herpes
usually HSV-2, but can be 1 DNA virus on PCR test or IgG serology few weeks of red bumps or tiny white blisters -> rupture -> ulcer pain, itchy detrimental to fetal developlment
herpes histo
can visualize blisters/ulcers with multinuclear giant cells with nuclear inclusions
test for herpes
Tzank test which uses pap stain best way to Dx is to see multinucleated giant cells with intranuclear ground glass viral inclusions
common causes of vaginitis
C. albicans (yeast infection) Trichomonas vaginalis Bacterial vaginosis (gardnerella)
C. albicans
not considered STD may be normal flora DM, abx, pregnancy, and immunosupressed at risk
Dx with KOH prep or pap
S&S of C. albicans
leukorrhea, pruitis, erythema
Trichomoniasis
flagellated protozoan STI (4d-4wks) motile
yellow froathy discharge, pruitis, dysurian, dyspareunia, strawberry cervix

strawberry cervic
seen in trichomonas vaginalis vaginitis
mycoplasma
vaginitis and cervicitis
implicated in spontaneous abortion and chorioamionitis

molluscum contagiosum

molluscum contagiosum
molluscum contagiosum
pox family virus
painless bumps
if scratch open and can spread via contact (towels)
usually resolves in 6-12 months, keep covered
can be STI in adults
Not a blister, central area of lesion is concave

mulluscum contagiosum
cytoplasmic pink inclusions representing clusters of large virus with nucleus pushed to the side
central concavity can be seen
PID definition
infection of pelvic organs beyond the uterine corpus
most common causes of PID
gonorrhea and chlamydia
most infections are polymicrobial
complications of PID
rupture of tuboovarian abscess
infertility form scarring of tubes
ectopic pregnancy
intestinal obstruction from fibrous bands and adhesions
subclinical PID
common cause of serious sequelae
up to 1/3 of infertility women w/o Hx of PID have underlying chlamydia infection
fitz-hugh curtis syndrome
perihepatitis
infection of liver capsule and peritoneal surfaces
can be complication of PID
salpingitis
fallopian tube plicae expanded by inflammatory infiltrate and edema
if acute filled with neutrophils, if chronic filled with plasma cells
bartholin gland cyst
obstuction of duct -> cyst
common
all ages can become infected
may be polymicrobial or gonorrhea or chlamydia
Tx must place catheter or sew open to allow continuous drainage

lichens planus
pruitic, polygonal, purple, plaques
usually symetrical
ususally goes away in 1-2 yrs, so just tx itch

wickhams striae of lichen planus

lichen planus
note band of chronic inflammatory cells at dermal-epidermal jnx
also squamous epi is normal thickness

lichen sclerosus aka LS&A
elderly and post menopausal females
unknown etiology, maybe autoimmune
atrophic change
not considered precancerous, but 4% increased risk of CA development

lichen sclerosis

lichen sclerosis
note white ‘parchment like’ areas

lichen sclerosis
no band of inflammatory cells, rather a significant band of hylinization
also thickened epi layer

lichen simplex chronicus
squamous hyperplasia and acanthosis
NO CYTOLOGICAL ATYPIA (if there were is would be VIN)
usually dt chronic scratching

LSC
CONDYLOMA ACUMINATUM
venereal warts
90% HPV 6,11 (low risk)
10% HPV 16,18,33 (high risk for VIN 2-3 and carcinoma)
gross appearance of Condyloma Acuminatum
frequently multiple and papillary warts, occasional flat
histo of Condyloma Acuminatum
koilicytosis, mitoses
Tx of Condyloma Acuminatum
cryo, chemical, laser, or excision

Condyloma Acuminatum
note flat white leukoplakia and multifocal
on histo exam would see hyperkeratosis, thickened epi, and peri-nuclear clearing

condylomata
warty type
cauliflower multifocal papules

condylomata
coalescing papules aka bowenoid papulosis
typical in low grade infections

koilocytosis of Condyloma Acuminatum
radinoid nuclei with surrounding cleared area
low grade infection
if high grade would also see nuclear enlargement
VIN
vulvar intraepithelial neoplasm
1-3
3 = CIS
VIN 1-3 determination
determined by what thickness has been invaded with nucelar enlarged cells
moderate (VIN2) = half thickness
if VIN 2 or 3 must be excised
invasice SCC of vulva
90% of invaseive vulvar CA
usually presents as nodules/masses on background of leukoplakia
an ulcerated mass is CA until proven otherwise
type 1 SCC of vulva
60%
warty and bowenoid type
HPV 16,18, 33
occurs in reproductive age women
type 2 vulvar SCC
40% keratinizing type
not HPV associated
may occur in long-standing LS&A or chronic inflammation
spread of SCC
local invasion with lymphovascular spreas to region nodes followed by mets to lung, liver, etc
tx of SCC
VULVECTOMY AND LYMPHADECTOMY
Glandular lesions of vulva
accessory breast tissue along milk line
papillary hidradenoma
extramammary paget disease
papillary hidradenoma
sharply circumscribed nodule in vulva with normal overlying skin
considered benign
has 2 layers of cells (columnar and myoepithlium)
extramammary pagets disease
presents as pruitic, red, crusted sharply demarcated area on labia majora of elderly
unlike paget disease of breast, does not have underlying carcinoma tumor mass, but IS malignant
aride form primitive germinal cells of mammary like gland ducts in skin
Dx pagets
halo cells (epidermal appendages)
PAD, Mucin, CEA, EMA, all postive
usually confined to epi and skin appendages
low potential for mets
Tx of pagets
wide local excision
may recur
look for synchronous tumors of breast, rectum, bladder, ovary
malignant melanoma
usuallly poor prognosis
S-100 and Melanin-A +
DES
given to women with miscarriages 40s-70s
it affects adenosis (process by which glandular epi of embryo is replaced by squamous)
some affected daughters developed CCC of vagina
also have increased risk for CIN and VIN and maybe breast CA
generalizations of vaginal neoplasms
80% mets
most primary are SCC which arises from Vaginal intraepithelial neoplasm (VaIN)
almost all d/t HPV16
Embryonal rhabdomyosarcoma
neoplasm of girls <5
presents as polypoid mass or vaginal bleeding
arises in lamina propria
high rate of surgical cure if <3cm
local invasion -> local nodes -> mets
frequently misdiagnosed as inflammatory polyps
can see mm spindle cells w/very small nuclei
