ABSTRACTBackground: Airborne contact dermatitis is considered in many cases as an occupational disease. Diagnosis is made with a positive photo-patch test in order to identify specific allergens. We report our experience at DR. MANUEL GEA GONZÁLEZ General Hospital.
Methods: A descriptive, open, prospective and transversal study was used. Thirty-two patients with diagnosis of contact dermatitis with at least six months of evolution were included. Patch tests were applied using the European plant and Scandinavian photopatch series from Chemotechnique Diagnostics Company.
Results: Nine patients (29%) had a positive result with the photo-patch test. Perfumes and usnic acid were the most frequent allergens. Eight individuals (25.8%) in the plant series and 28 in the standard series tested positive (90%).
Conclusions: The frequency of airborne contact dermatitis was 54.8% when included standard, plant and photopatch series. The most important etiological agents were plants, perfumes, potassium dichromate, and Balsam of Peru. Thus, the application of standard, plant and photo-patch series is important for the diagnosis and treatment of these patients.
