Allergic contact dermatitis due to benzyl peroxide from an unlikely source

Introduction: Benzoyl peroxide (BPO) is a substance commonly used for treatment of acne. However, it is also present in other sources, such as hair bleaching treatments, teeth whitening agents, and bleached flour. Although irritant contact dermatitis secondary to BPO is common, allergic contact dermatitis is rare. Here, we present a baker who developed allergic contact hand dermatitis to BPO in bleached flour.
