Abstract

Allergic contact dermatitis (ACD) of the vulva arises as a primary condition or develops secondary to topical agents. We aimed to describe the incidence of ACD in patients presenting with vulvar symptoms and to identify the allergens of most importance.Using a database of the patch testing results from 3 geographically distinct sites, we identified patients tested to a gynecologic series between 2003 and 2010. Patients had patch testing to the standard European battery and a gynecologic series. Patch testing was in line with accepted universal methods: application on day 1, allergen removal and initial reading on day 3, and final reading on day 5.Ninety patients were included. Thirty-five (39%) had a relevant positive result. The 5 allergens with the highest number of cases with a relevant reaction were natural fragrance mix 2%, balsam of Peru, benzocaine 5%, fragrance mix 8%, and quaternium 15 1%. The most common gynecologic series allergen to cause a relevant reaction was terconazole.Allergic contact dermatitis is a frequent finding in patients presenting with vulvar symptoms. We identified a relevant positive result to patch testing in 39%. We found fragrances, medicaments, and preservatives to be of most relevance.
