Female Flashcards
Vulvovaginal pathology
can be divided into two broad categories:
Non-neoplastic: include infections (STDs and non-STDs) and lekoplakias
Neoplastic: include in situ cancer, invasive (squamous and adeno) and sarcoma
2 viral STDs:
HSV2, HPV
usually causes genital lesions
HSV2
How do ulcers form in HSV2?
red papules –> vesicles –> painful ulcers
latency in the lumbosacral cranial nerves, can be reactivated any/many times, high transmission during active phase
HSV2
HPV is a _____ virus.
DNA
Many subtypes/strains of HPV: low-risk vs high-risk
“Low-risk” strains (6 and 11 most common) associated with wart-like lesions (condyloma)
- Vulva, perineal, and perianal region
Infection with “high-risk” strains (16 and 18 most common) is a risk factor for developing dysplasia and cancer (squamous cell carcinoma) of the genitals and cervix
What does the Gardasil vaccine provide protection against?
nine HPV strains: 6, 11, 16, 18, and 5 other high-risk strains
Histology: exophytic, papillary proliferation of squamous epithelium
HPV
histology: koilocytes
HPV
*Koilocytes = cells with clear cytoplasm and condensed, shriveled nuclei (a morphologic sign of an HPV-infected epithelial cell)
flagellated ovoid protozoan, asymptomatic or frothy yellow vaginal discharge
Trichomonas vaginalis
Clinical appearance: fiery red mucosa of the vagina and cervix (strawberry cervix)
Trichomonas vaginalis
bacterial infection—coccobacillus, fish odor, thin grey secretions
Gardnerella vaginalis
Histology: clue cells (vaginal epithelial cells covered in bacteria)
Gardnerella vaginalis
a clinical term used to describe an adherent white plaque, the white color is usually attributable to increased keratin production
leukoplakia
may represent many possible conditions including hyperplasia, dysplasia, and squamous cell carcinoma
leukoplakia
vulvovaginal neoplasms
VIN1-VIN3 / VAIN1-VAIN3 / CIN1-CIN3 –> vulvar/vaginal/cervical intraepithelial neoplasia
vulvovaginal neoplasm grading
the 1-3 grading is based on how much of the thickness of the epithelium is involved, with 3 being the most
