Systemic contact dermatitis due to compositae

Brian C. Machler, Chandler W. Rundle

 A 62-year-old-woman presented with dermatitis of the face, eyelids, and neck. Patch testing results after 96 hours revealed positive reactions to benzoyl peroxide, 2-n-octyl-4-isothiazolin-3-one, compositae mix II, and propylene glycol. Upon further evaluation of her history, it was found she had regular ingestion of sunflower butter, dandelion teas, artichokes, and Echinacea tablets. After complete clearance of the substances, her dermatitis cleared. Re-exposure to these edibles led to recurrence.
