Disorders of Vulva & Vagina Flashcards
External vulvar anatomy
- boundaries
- structures included
- Boundaries extend from mons pubis to anus to labial cural folds
- Structures include: Labia majora, labia minora, paired Bartholin’s glands, Skene’s glands, urethra, anus, clitoris
Lymphatic drainage of vulva
- Lymphatics of vulva drain from posterior to anterior traversing thru the mons pubis and into superficial and deep inguinal nodes
- Tend to drain to ipsilateral side
What is the function of bartholin glands?
Secrete mucus for lubrication
What are the 3 tissue types and locations that make up bartholin glands?
- Proximal = glandular epithelium
- Distal = transitional epithelium
- Opening = squamous epithelium
What causes a bartholin gland cyst?
Orifice of gland may become obstructed leading to mucus accumulation and cystic dilatation.
Characteristics of bartholin gland cyst
- unilateral
- soft, painless mass
Which population should always have an excision of a bartholin gland cyst?
women over 40 to exclude carcinoma
How is a bartholin abscess different from a bartholin gland cyst?
-the cyst is now infected
Characteristics of bartholin gland abscess
- very painful
- fluctuant, swollen, red, warm, mass
Tx of bartholin gland abscess
I&D with culture, consider drain placement (Word catheter)
What is a word catheter?
- catheter that is placed into the area of the now empty abscess
- it is inflated and left in place for 4-6 weeks
- this promotes the formation of an epithelialized tract for drainage
Marsupialization of Bartholin Gland Abscess
- Abscess cavity is incised 1-2 cm in length and drained
- The edge of the cyst wall is grasped and everted open
- The opening is then sutured open creating a new larger duct for drainage
List the non-neoplatic disorders (4)
- Lichen Sclerosis
- Lichen Simplex Chronicus/Squamous Cell Hyperplasia
- Lichen Planus
- Vulvar Psoriasis
What is the most common vulvar derm disorder?
Lichen sclerosis
Etiology of lichen sclerosis
- Chronic, relapsing and remitting disorder (inflammatory)
- Peak Onset: Pre-pubertal and postmenopausal women
Appearance/sx of lichen sclerosis
- *Figure 8/hourglass appearance**
- Lesions appear as smooth, white plaques.
- Surface is smoothed and resembles parchment or wrinkled cigarette paper.
- Sx: intense pruritis, pain, dyspareunia
Etiology and anatomy of lichen sclerosis
Etiology is unknown:
- Autoimmune
- Genetic
- Hormonal
- labia minora, labia majora, clitoris, and perineum can all be involved
- vagina is spared
Dx/Tx of lichen sclerosis
Diagnosis made by punch biopsy.
-Repeat biopsy if new lesions/symptoms as these patients are at increased risk for vulvar cancer.
Treatment:
- Patient education
- Topical corticosteroids
- -Applied BID/daily until symptoms are controlled.
- -Then 1-3 x weekly for maintenance.
List the drugs for tx of lichen sclerosis
- Topical tacrolimus (Protopic 0.03 or 0.1%) or pimecrolimus (Elidel 1%) demonstrated effective but mainly use with taper.
- Recalcitrant: oral hydroxychloroquine or cyclosporin
Etiology of Lichen Simplex Chronicus
- AKA squamous cell hyperplasia – NOT a malignant precursor**
- Secondary to chronic rubbing/scratching.
- Associated with pruritis
- Mostly in premenopausal women
- Typically found on hair-bearing areas of labia majora
Describe clinical findings of lichen simplex chronicus
- Characterized by benign epithelial thickening and hyperkeratosis from chronic irritation
- Skin is thick with exaggerated skin markings
- Usually bilateral and symmetric
- *not a distinct entity but rather a description of morphologic alterations of vulva.
Dx/Tx of lichen simplex chronicus
Diagnosis is again made by biopsy.
Treatment:
- Patient education
- Identify and treat cause of itching (infection, contact dermatitis, etc.)
- Topical corticosteroids
Etiology of Lichen Planus
- Rare disorder believed to be autoimmune.
- Affects skin and mucous membranes
- Commonly affects the groin and the mouth**
- Leads to intense pruritus, burning, dysuria, dyspareunia, and post coital bleeding
- Mostly affects postmenopausal women
- Almost 70% of patients have vaginal involvement
What is lichen planus characterized by??
Lesions characterized by bright erythematous erosions with white striae or white border (Wickham’s striae) visible along the margins
