Contact dermatitis of the vulva.

Contact dermatitis of the vulva is common, with irritant contact dermatitis occurring more frequently than allergic contact dermatitis. Patients with chronic vulvar dermatoses are at greater risk and should continually be reassessed for possible contact dermatitis. Comprehensive and specific questioning about hygiene practices and product use is necessary to elicit a history of contactant use. Patch testing is required to identify relevant contact allergens, the most common of which include medicaments, preservatives, and fragrances. Patient education and follow-up are essential in optimizing treatment and preventing recurrence of vulvar contact dermatitis.
