Abstract
Objective: Allergic contact dermatitis (ACD) is a hypersensitivity reaction which develops against substances contacting the skin. Patch tests are used for the detection the allergens that cause ACD. The most common substances that cause ACD vary based on geographic regions. In this study, detection of the most common allergens in patients who underwent patch testing with the diagnosis of ACD and comparison of the results with literature were aimed.Mateials and Methods: One hundred forty-eight patients, who underwent European standard patch test with the diagnosis of ACD in our clinic between January 2010 and June 2013, were enrolled in our study. The data about age, sex, duration of disease, occupation, the presence of atopy, localization of the lesion of the patients and patch test results were recorded retrospectively.Results: Eighty-nine females and 59 males, a total of 148 patients, were included in the study. The mean age of the patients was 35.3 ± 14.8. Positive reactions to one or more allergens were observed in forty-five (30.4%) of 148 patients who underwent patch test. The allergens that were the most common cause of positive reactions were nickel sulfate (11.5%), potassium dichromate (6.1%), cobalt chloride (4.7%), paraben mix (4.1%), thiuram mix (2.7%), neomycin sulfate (2.7%) and fragrance mix (2.7%), respectively. Conclusion: We believe that our study will contribute to the determination of contact allergens which is the most common cause of sensitization in our country
