Abstract | BACKGROUND: Patch testing with benzoyl peroxide 1% pet. frequently leads to (weak) positive reactions, often with uncertain clinical relevance. OBJECTIVES: To describe the pattern of patch tests reactions to benzoyl peroxide and to identify patients at risk of a positive reaction. METHODS: Retrospective analysis of data from the Information Network of Departments of Dermatology (IVDK), 1992-2007. RESULTS:
Benzoyl peroxide 1% pet. was tested in 29 758 patients. Weak positive reactions ( erythema, infiltration, possibly papules) occurred in 6.5%, and strong positive reactions ( erythema, infiltration, vesicles) in 1.3%. According to logistic regression analysis, strong positive reactions to benzoyl peroxide were associated with leg or face dermatitis, work as dental technicians, young age and being female. Patients with atopic dermatitis had a significantly increased risk of weak positive reactions only. CONCLUSIONS:
