title: Allergic contact dermatitis from purified eosin.
abstract: We report on a patient, seen in 1993, who developed sensitization to eosin from topical preparations. The patient had a positive patch test reaction to pure tetrabromofluorescein but not to its impurities separated by thin-layer chromatography. Our findings suggest that the allergen was eosin itself.
