Synopsis
Contact dermatitis of the vulva is more often of the irritant type, rather than allergic, due to the persistent moisture and maceration in the genital region.
Soaps, detergents, antiseptic solutions, and topical medications are often the source of irritation. Prolonged or recurrent exposure to an irritant often causes the skin to become lichenified, hyperkeratotic, and inflamed.
Early in the course of irritant contact dermatitis, patients typically present complaining of a burning or stinging; the symptoms and skin eruption usually follow the exposure by hours if the irritant is strong (whereas in allergic contact dermatitis, symptoms are usually delayed by approximately 2 days following exposure). As the irritation becomes chronic and the skin continually inflamed, pruritus can become a predominant symptom.
