H&P - aggravating/alleviating, new things, severity/duration (acute vs chronic). If acute, rule out infections (BV, trich, candida, scabies). IF chronic, rule out (dermatoses and dysplasia).

If pain, see if associated pruritis. I
f pruritis + pain, dermatoses or vaginal atrophy.
IF just pain, vulvodynia.

30
Q

When should you do a vulvar biopsy? How is it done?

A

Atypical lesion (new pigmentation, bleeding, ulcerated, affixed)
Concern for malignancy
Lesion in immunosupcomprimsed
Doesn’t respond to standard therapy or gets worsed
Stable lesions that rapidly increase in size

punch or excisional biopsy.

31
Q

How does patient with contact dermatitis present clinically?
What is the treatment?

A

Range of symptoms: Mild erythema, swelling, scaling, fissures, erosions, ulcers. Typically associated rash.
Chronic itching/burning
Type 4 delayed hypersensitivity
Treatment: vulvar care/removal of irritants, topical corticosteroids and oral antipruritic meds prn. AVOID topical antipruritic (benadryl) bc can cause allergic contact dermatitis.

32
Q

How does lichen simplex chronicus present?
What is treatment?

A

chronic/intermittent prutitis w/ scratching/rubbing
Erythematous scaling or lichenified plaques.
Thick plaques w/ hyper and hypopigmentation. Erosions/ulcers develop from chronic scrapping

Hx allergies, asthma or eczema.

Ddx: clinical. Consider vaginal fungal culture to r/o candidas

Treatment: vulvar care/hygiene, antipruritic meds, topical medium or high potency corticosteroid once or twice daily.

How often to follow up on pts using high potency topical corticosteroids: schedule close interval follow up 4 wks post initiation. Additional visits based on pts response to therapy. Tx failures from use of low-potency or shorter than recommended use of high potency steroids

33
Q

How does lichen sclerosis present clinically?

A

Chronic scarring affecting anogenital skin of postmenopausal woman and pre-pubertal girls.
Exam w/ porcelain-white papules/plaques with area sof ecchymosis. Skin is thin, whitened, crinkled (cigarette paper)
Involvement of mucutaneous junctions → introital narrowing. Involves superior vulva to perianal tissue to create “figure of eight” shape
Fusion of labia minora, fissures.

Ddx: Biopsy. Incr risk squamous cell carcinoma (2-5%). Tx=medium or high potency topical corticosteroids. Clobetasol propionate 0.05 ointment qhS x 4 weeks, alternate nights for 4 weeks then twice weekly for 4 weeks.

34
Q

What is follow up for lichen sclerosis?

A

Monitor at 3 months. Then follow up 3-6 mo later. Biopsy any new growths.

Do you need long-term maintenance therapy: long-term individualized topical corticosteroid to prevent scarring. Titrate to lowest dose needed.

How do you treat resistant/poorly controlle cases? Intra-lesional corticosteroids injections. 10-20mg intralesionsal triamcinolone.
If no response to intralesional corticosteroids? Topical calcineurin inhibitors (tacrolimus or pimecrolimus)
What if calcineurin inhibitors fail? Refer to specialist.

35
Q

How does lichen planus present clinically?

A

Scarring inflammatory disorder. sx=dyspareunia, burning, soreness, itching, incr vaginal discharge
Affects perimenopausal/menopausal
Up to 70% have oral involvement

Types: Classical (white, reticulate, lacy, fernlike striae), hypertrophic (least common, white thick), Erosive (Deep, painful erosions and extend to labia minora - can cause oblieration of vaginal space. INVOLVES VAGINA. Eval of oral cavity recommended) - refer to oral specialist.

Ddx: clinically. Vaginal discharge w/ predominance of inalmamtory cells and parabasal/basal cells. Incr vaginal pH (5-6). Biopsy is non-specific

Treatment: prognosis for remission is poor. High-potency topical corticosteroids: twice daily use w/ tapering.
How often to follow up? 2-3 mo.
How to treat resistance disease? Topical calcineurin inhibitors.
How to treat if vaginal involvement: if erosive w/ vaginal involement, intravaginal corticosteroids (hydrocortisone acetate suppositories inserted twice daily and tapered off). 80% pts will have improvement. Can use vaginal dilators to prevent scarring/obliteration.
How to treat extensive vaginal disease? High-dose hydrocortisone inserts.

36
Q

What is the classification of VIN?

A

Vulvar LSIL/HSIL: warty, basaloid, mixed - associated w/ genotypes of HPV and risk factors (smoking, immunocompromised)
Differentiated: NOT assoc w/ HPV. assoc w/ vulvar dermatoses. If have lichen sclerosis, likely to be associated with SCC.

New terminations: usual type is now vulvar HSIL. flat lesions assoc w/ basal atypia are LSIL (condyloma or HPV effect).

37
Q

How do you diagnose VIN?
When do you colpo warty lesions?
How do you treat VIN?

A

Visual assessment. Biopsy if needed - only if not responding to usual therapy.

Determine extent of disease if persistent pruritis/pain and if symptomatic despite treatment
Apply 3-5% acetic acid to vulva using soaked gauze pads.
- COLPO!

WLE if cancer suspected bc risk invasion (Include gross margins of 0.5-1cm around tissue w/ visible disease. If critical area lesion, refer to specialist.
- If occult invasion not a concern, vulvar HSIL (VIN usual type) treated w/ :
- excision
- laser (1mm in non-hair bearing and 3mm in hair-bearing areas)
- topical imiquimod 5%.

38
Q

When do you use laser ablation in VIN?

A

Treatment of vulvar HSIL when cancer NOT suspected.
Need 0.5-1cm margin of normal appearing skin to be treated. Need to destroy cells through entire thickness of epithelium.

39
Q

What is suggestive of vulvar cancer on physical exam?

A

Exophytic, ulcerative, indurated, poorly-defined borders

40
Q

What are steps of WLE?

A

– just know basics.

An indwelling bladder catheter is placed. The incision can be marked with a skin-marker to plan the extent and axis of the excision. The shape of the excision should be elliptical, running in long axis parallel to neighboring structures to be preserved

we start posteriorly so that venous oozing from the incision does not affect visualization in the direction of travel. The excised portion of the incision is grasped with a toothed forcep or Allis clamp and consistent tension is applied, allowing the operator to elevate and stretch the skin (figure 4). The epidermis, dermis, and underlying adipose tissue are dissected from the underlying perineal tissues using scissors, scalpel, or electrocautery.

41
Q

What is a wet prep?

A

A vaginal wet mount preparation is a test where a sample of vaginal discharge is observed by wet mount microscopy.

  • The swab collected sample is placed on a clean glass slide and mixed with either 0.9% saline or 10% potassium hydroxide (KOH).
  • Saline preserves cell membranes and allows observation of motile trichomonads, and vaginal epithelial cells coated with bacteria (clue cells), and white blood cells (WBCs).
  • If a yeast infection is suspected, the addition of 10% KOH will hydrolyze trichomonads, cells, and bacteria to provide a clearer view of yeasts and pseudohyphae. In many cases of BV or trichomoniasis infection, addition of KOH to the vaginal discharge will produce a strong amine or fishy odor.
42
Q

What is vulvar melanoma?

A

rare, accounts for 5-10% melanoma in women.
- BRCA2 AT INCREASED RISK
- avoid lots of sun exposure, need regular physical exams.
- eval w/ colposcopy. can do biopsy.

43
Q

What is treatment for genital warts?

Risk factors for genital warts?

A

Cryotherapy, TCA, surgical removal. Imiquinod=immune response modifier. Applied 3x/week until warts are gone.

HPV, increased # sexual partners, on oCPs, smoking
