Introduction Most usful means of generating

differential diagnosis is by morphological findings rather than symptomatology

Vulvar biopsy should be performed if the lesion is clinically suspicious or does not resolve after standard therapy

Vulvar SymptomsVulvar Symptoms Most often,primary vaginitis and Most often,primary vaginitis and

secondary vulvitissecondary vulvitis

A number of skin conditions on A number of skin conditions on other areas of the bodyother areas of the body

Neoplasia Vulvar intraepithelial neoplasia a precancerous lesion that may progress to

invasive cancer

Most are raised multifocal white (may be red or pink) and/or verrucous lesions

Cancer presents with unifocal vulvar plaque,ulcer or mass

Lichen scerosus and erosive lichen planus predispose to cancer

Genital warts Caused by human papillomavirus Flat,filliform or verrucous,or giant Flesh colored or pigmented Biopsy is indicated if there is rapid

growth,increased pigmentation,ulceration,pigmentation,fixation or poor response to therapy

Treatment : trichloroacetic acid, podophyllum,Cryo,laser

Not curative ,merely speed clinical resolution

White patch Lichen sclerosus,well demarcated

white finely wrinkled and atrophic patches

Vulvar itching and typical findings Potent topical corticosteriod

ointment Close follow up for risk of

malignancy
