Association of contact urticaria and allergic contact dermatitis to rubber.
We present a case of a healthcare professional that developed type I and IV hypersensitivity reactions to rubber. During the clinical examination the patient showed eczematous dermatitis of the hands. The patch test was positive for thiuram group and an open test with a piece of glove was positive after 20 minutes of exposure. Allergen-specific IgE test (RAST) was relevant. Reactions to rubber allergens are frequent among healthcare professionals due to constant contact with this material.
