title: Erythema multiforme reaction to patch testing.
abstract: A young woman developed erythema multiforme in association with multiple patch test reactions. Sequential patch testing revealed 2 true positive reactions (colophony and fragrance mix), and was not associated with flare of erythema-multiforme-type lesions. The development of erythema multiforme should be included in the list of possible adverse reactions to patch testing, albeit a rare occurrence.
