Cervix vagina vulva path Flashcards
lichen simplex chronicus
secondary to chronic inflammation and itching
thikened hyperketatoic and white plaques
thikened epithelium with chronic inflammation
NO known prediliction for carcnoma
invasive sqaumous cell carcinom of vaginaa preceded by
vulvar dysplasia (VIN)
reactive changes (lichen sclerosus)
HPV vaccine makeup
HPV l1 protein, th major capsid protein of HPV
sqaumocolumnar junction =
trasnformation zone
vulvar intraepithelial neoplasia (VIN) =
precancerous lesion of vulva
high risk HPV
(VIN 1-3 depending on dysplasia)
progression to squamosu cell carcnionma
sqaumous cell dysplasia of vagina =
VAIN (1-3)
possible porgression to squamous carcinoma
quadravalent HPV vaccine covers
6 11 16 18
extrammammary paget’s disease =
red scaly plaques on labia
characterized by large pale glandular cells in epidermis
dysplaysia in CIN characterized by
nuclear atypia
ncreased N:C ratio abundant mytoses
cervical pap smear cytology screening begins at
21
cotesting with/without HIgh risk HPV after age 30
endocervical polyps morphology
glandular or metaplastic squamous lining
dilated glands with mucus
may blled (ulceration or infalmmation)
no malignnat potential
sarcoma botryoides (embryonal rhabdomyosarcoma) presentation and appearance
infants and young children
soft, polypoid masses in vagina
urinary bladder and bile ducts also possible
characterized by primitive cells
HPV pathogenesis
squamous cell strains replicated DNA ? express E6 and E7
E6 binds p53, E7 binds Rb > promote growth and carinogenesis
