Protein-contact eczematous reaction to cornstarch in clothing.

Protein contact dermatitis is an eczematous reaction to antigens often associated with immediate hypersensitivity. A patient with a history of atopic eczema and multiple immediate sensitivities was seen for a persistent dermatitis of the face, hands, and clothing areas of the trunk and arms. Investigation showed a positive prick test to cornstarch, and avoidance of glove powder and starch in her clothing cleared what had been a recalcitrant problem.
