Four patients with occupational contact dermatitis to Lactuca sativa had cross‐sensitivity to Cichorium endivia. One of the patients also had contact urticaria to Lactuca and Cichorium , and another reacted positively to scratch tests with these plants as a sign of immediate allergy. In two cases such immediate allergy was considered the cause of a vesicular, intense itching eruption within a few minutes of contact with fresh leaves of Lactuca on previously eczematous skin. The severe chronic dermatitis of the hands of these patients is ascribed to combined delayed and immediate allergy.
