Vulvar and Ovarian Disease Flashcards
What is lichen sclerosus?
Autoantibodies attack extracellular matrix and basement membrane (immune dysfunction affecting all levels of the skin)–poorly understood so can be genetic or enviromental too
Environmental factors affecting pathophysiology of lichen sclerosus
Incontinence
Infection
Contact dermatitis
Trauma (Kobners phenomenon)
Presentation of lichen sclerosus
Mostly in postmenopausal women
Most common sxs is pruritus!!!
Pain (dysuria and dyspareunia)
What is seen on PE for lichen sclerosus?
Sharply, well-demarcated white plaques
Usually begins periclitorally with spread to perianal skin
(not usually seen as keratinized, hair-bearing labia majora or mucus membranes)
Pathognomonic for lichen sclerosus
Plaques demonstrate “cellophane paper” (also waxy and/or hyperkeratotic apperance)
Hallmark of lichen sclerosus
Fragility (purpura, erosions and fissues)
What can occur in untreated lichen sclerosus?
Squamous cell carcinoma (small amt)
Can also see pigmentary changes (benign but can see aytpical nevi and melanoma and take the pigmented lesions seriously)
Hypothyroidism
Risk factors of developing SCC from lichen sclerosus
Elderly
Hyperkeratotic lesions!!
How to confirm diagnosis of lichen sclerosus
Vulvar punch biopsy
Tx for lichen sclerosus
Topical ultrapotent steroid ointment!!! (first line is temovate .05% ointment applied twice daily until normal texture and can use 1-3x week for maintenance)
Lifelong!!!-thicker skin so can handle the steroid for a while
Side effects of temovate steroid for lichen sclerosus
Atrophy, dermatitis and rosacea
Other tx options for lichen sclerosus
Can use topical estrogen also but does not go away
What are Bartholin ducts?
Bilateral glands at 4 and 8 o clock positions in labia minora–ducts open into vestibule adjacent to vaginal introitus–secrete mucus like material to maintain moisture of vaginal mucosa
Pathophysiology of Bartholin cyst
Cysts form as result of ductal obstruction due to trauma or non specific inflammation
Abscess formation from infected cyst or primary gland infection (polymicrobial, STIs)
Presentation of Bartholin cyst
Acute, painful unilateral labial swelling
Dyspareunia
Pain with sitting or walking
What is seen on PE for Bartholin cyst?
Tender, fluctuant labial mass Surrounding erythema and edema Cellulitis Abscess formation Fever
Tx for Bartholin cyst
I&D with insertion of Word catheter Culture purulent material Empirical abx therapy (Keflex or Doxy) Sitz baths for 2-3 days No intercourse until cath is removed
Possible pathophysiology of vulvodynia
Estrogen conc (onset around menopause, affects pain sensitivity and sensory discrimination) Pelvic floor dysfunction Psych (mood/anxiety disorders, poor allostasis) Neuro sensitization (insult to vulvar mucosa causes chronic inflammation and sensation of touch becomes painful)
Presentation of vulvodynia
Vulvar discomfort described as burning sensation (stinging, irritated, sore, raw, stabbing)
Introital pain with intercourse
Generalized vs localized (sexual or nonsexual etc)
Important parts of PE for vulvodynia
Use Q tip to palapate vestibule, labia majora, perineum or interlabial folds
Pain is limited to vestibule
Single digit exam to feel for spasm or tenderness of pelvic floor musculature
Non-specific vestibular erythema
Tx for vulvodynia
No scented products, tight clothing, vigorous exercise or pads
Sitz baths BID followed by petroleum jelly
Couple counseling
Pelvic floor PT
Local nerve block
Pharm meds for vulvodynia
Topical vaginal estrogen .03% with T .1%
Nortriptyline 50 mg QHS (titrate up starting at 10)
Gabapentin 1200 mg TID (titrate up to it)
What is vulvar intraepithelial neoplasia?
Neoplastic cells confined to squamous epithelium
How to classify vulvar intraepithelial neoplasia
1, 2 or 3 (like CIN)
Now want to combine 2 and 3 b/c true precursors to vulvar cancer (Vinu and VINd based on morphologic manifestations)
Usual type of vulvar intraepithelial neoplasia
VINu
What is VINu associated with?
HPV 16 and 18 (seen in younger women so same risk factors as CIN)
Risk factors of CIN and VINu
Smoking
Immunosuppression
Multiple sex partners
How to diagnose VINu
Vulvar colposcopy: 3-5% acetic acid and let sit for 3-5 min Avoid using acetic acid in areas of inflammation and breaks in epithelium See raised or flat lesions Color is gray to white or red to black
Presentation of VINu
Most asymptomatic
Vulvar burning and pruritus in half
Association of VINu
High grade CIN (colposcopy is mandatory to rule out)
Biopsy all pigmented lesions!!
Tx for VINu
None provide a cure (reactivate latent)
All meds are off label
Off label meds for VINu
5FU cream (many s/es)
Interferon
Imiquimod 5% cream (apply 3 times weekly up to 20 wks so low compliance)
Must do vulvar assessments q 4wks during tx
Standard of care for VINu tx
Surgery: CO2 laser vaporization (destroy entire thickness of epithelium but don't do if invasion) Local wide excision Vulvectomy Some high recurrence
What is VINd?
Differentiated type unrelated to HPV (not have same risk factors)
Seen in older women (>70)
Involves lower 1/3 of epithelium (so none abnormal cells in upper)
Pathogenesis of VINd?
Associated with squamous cell hyperplasia (lichen sclerosus, lichen simplex chronicus)
Unidentified carcinogenic agents combined with local environment of chronically irritated/inflamed skin lead to dysplastic cells
Tx for VINd
Prevent: tx of underlying
Tx is surgical excision tho
Follow up for VINu and VINd
Vaccination with Gardasil (VIN usual type)
Women with history of VIN considered at risk of recurrence
Must do post tx follow up of colposcopic vulvar inspection at 6 and 12 mos and then annually after
Incidence of vulvar cancer
Very uncommon tho
Etiology in 20-40 YO is HPV related (VINu)
60-70 YO is due to chronic irritation and poorly understood co-factors (VINd)–most have untreated lichen sclerosus, lichen simplex chronicus or squamous cell hyperplasia
Co-morbidities of vulvar cancer
Some have type 2 DM
Some are obese or hypertensive
Presentation of vulvar cancer
Asymptomatic (delays diagnosis so inspect vulva)
Pruritus is most common sx
Vulvar bleeding and pain
PE of vulvar cancer: squamous cell carcinoma
Varies in appearance from large, exophytic cauliflower like lesion to small ulcerative lesions with surrounding hyperkeratosis
PE of vulvar cancer: basal cell carcinoma
Raised lesion with ulcerated center and rolled borders
PE of vulvar cancer: malignant melanoma
Seen at labia minora and clitoris
Raised, darkly pigmented lesion
Tx for vulvar cancer
Staging based on fIGO
Primary: complete surgical removal of tumor with inguinal node dissection
Radiation therapy with lymph node spread!!
Background of vaginal intraepithelial neoplasia (VAIN)
-Precancerous disease of vagina (rare!!)
Seen mostly 35-55
HPV must be present to develop VAIN
Some have been previously treated for CIN or hysterectomy
Risk factors of vaginal intraepithelial neoplasia
Smoking, multiple sexual partners and early onset of sexual activity (same as CIN)
History of CIN III
Pathogenesis of vaginal intraepithelial neoplasia
HPV exposure but requires long time to develop
Frequency not as high as CIN since vaginal epithelium is different than cervical
Not very high progression to invasive cancer
