The vulvaThe vulva
• Is the part of the female genital tract located between the genitocrural folds laterally, the mons pubis anteriorly, and the anus posteriorly.
• Embryologically, it is the result of the junction of the cloacal endoderm, urogenital ectoderm, and paramesonephric mesodermal layers.
• This hollow structure contains – LABIA MAJORA– LABIA MINORA– CLITORIS– VESTIBULE– URINARY MEATUS– VAGINAL ORIFICE– HYMEN– BARTHOLIN GLANDS– SKENE DUCTS.

The vulvaThe vulva
• Different epithelia, from keratinized squamous epithelium to squamous mucosa, cover the vulva.
• The labia minora are rich with sebaceous glands but have few sweat glands and no hair follicles.
• The epithelium of the vestibule is neither pigmented nor keratinized and contains eccrine glands.

• During early stages the patient may not have
symptoms.
• Some patients develop intractable pruritus
• Burning and pain are less likely manifestations.
• Figure-of-8 or keyhole configuration.
• In late stages normal architecture may be lost
– atrophy of the labia minora, constriction of the vaginal orifice
(kraurosis), synechiae, ecchymoses, fissures.
• Squamous cell carcinoma develops in 3-6% cases

• Etiology – Unknown. A higher prevalence of the disease in
postmenopausal women suggests hormonal factors, but this has not been confirmed.
– Studies identifying an infection are inconclusive – Weakly linked to autoimmune diseases and
genetic factors– Local factors (eg, trauma, friction, chronic
infection and irritation) – Recurrence near vulvectomy scars has been
observed.

Squamous HyperplasiaSquamous Hyperplasia
• ITCHING is a common symptom.
• If hyperkeratosis is not prominent, lesions may
appear as reddish plaques.
• The clitoris, labia minora, and inner aspects of the
labia majora are more commonly affected.
• Extensive lesions may result in stenosis of the
vaginal introitus.

Squamous HyperplasiaSquamous Hyperplasia
• Etiology
– Repetitive scratching or rubbing from
irritants
– Treatment is aimed at halting the
itch-scratch-itch cycle.

Squamous HyperplasiaSquamous Hyperplasia
• Treatment – The same as lichen sclerosus
– General attention to proper hygiene.
– If the skin is moist or macerated, aluminum acetate 5% solution applied 3-4 times daily for 30-60 minutes is beneficial.
– Systemic antihistamines or tricyclic antidepressants
– Refractory lesions, intralesional injections of triamcinolone acetonide may be an alternative.

lichen simplex chronicuslichen simplex chronicus
• Hyperkeratotic, usually ill-
defined, grayish, thickened,
and sometimes excoriated
lesion.
• Usually located over the labia
majora.
• Hyperpigmentation.
• Itching is always present and
may be intense.

lichen simplex chronicuslichen simplex chronicus
• Lichen simplex chronicus of the vulva is the end stage of
the itch-scratch-itch cycle. • The initial stimulus to itch may be:
– Underlying seborrheic dermatitis.
– Intertrigo
– Tinea.
– Psoriasis.
– In most cases, the underlying cause is not evident and may have been transient vulvitis or vaginal discharge.
• Any itching disease of the vulva may become secondarily lichenified.

lichen simplex chronicuslichen simplex chronicus
• Treatment
– Includes removal of irritants and/or allergens
– Topical application of mild-to-high–potency corticosteroids.
– Avoid soaps and cleansing agents other than aqueous cream.
– Discourage excessive cleaning of the genital area; use of hot
water; overheating; and wearing of synthetic, rough, and/or
tight clothing.
• Lichen simplex chronicus may be associated with
underlying diseases (eg, Paget disease, Bowen disease)

Lichen planusLichen planus
• Three types:
– Papulosquamous– Erosive – Hypertrophic
• Malignancy is possible in long-standing and ulcerative lichen planus.

Lichen planusLichen planus
• The papulosquamous form: – Occurring as part of a
generalized disease – Is the most common and is
characterized by:• Flat-topped• Polyhedral, • Violaceous, shiny, and itchy
papules located on keratinized skin of the labia and mons pubis. Delicate and whitish reticulated papules may be present on the mucosa, but no atrophy or scarring is observed.

Lichen planusLichen planus
• The erosive form:– Involves the mucous membranes of the mouth and
vulvovaginal area and may be locally destructive, leading to atrophy and scarring.
– Synonyms include erosive vaginal lichen planus, desquamative inflammatory vaginitis, vulvovaginal-gingival syndrome, and ulcerative lichen planus.
–Itching is rare, but pain, burning, and irritation occur and may be responsible for dyspareunia and dysuria.

Lichen planusLichen planus
• The rare hypertrophic form:– Resembling lichen sclerosus,
manifests with extensive white scarring of the periclitoral area with variable degrees of hyperkeratosis.
– It may be very itchy. – Extensive vaginal involvement may
result in a malodorous discharge. – Large denuded areas may become
adherent, causing stenosis of the vaginal introitus and dyspareunia.
– Marked atrophy may develop with time.
