Occupational contact dermatitis from <i>Cichorium</i> (chicory, endive) and <i>Lactuca</i> (lettuce)

Abstract

In two cases, occupational contact dermatitis was found to be due to chicory (Cichorium) used as a salad plant. In one of the two cases, contact sensitivity to letuce (Lactuca) was also observed. The sesquiterpene lactones of the plant may be the allergens.
