Systemic contact dermatitis--kids and ketchup.
Systemic manifestations of allergic contact dermatitis due to consumption of foods containing balsam of Peru (Myroxylon pereirae)-associated chemicals have recently been reported in children. We present seven children with widespread, recalcitrant dermatitis who experienced 60-80% clearance after initiating a diet low in balsam of Peru, specifically the tomato product ketchup. Furthermore, because we have observed a high prevalence of ketchup in our pediatric patients' diets, we recommend consideration of moderate consumption of this product in patients with recalcitrant widespread dermatitis.
