Clinical Significance
Watermelon may uncommonly induce symptoms of food allergy in sensitized individuals. Allergic reactions include oral allergy syndrome or oropharyngeal symptoms (itching and/or swelling of the lips, tongue, or throat), urticaria, dermatitis, angioedema, and dyspnea. Allergens produced by watermelon are an important cause of IgE-mediated sensitization. The presence of allergen specific IgE antibodies in serum of a patient is highly predictive of the likelihood that the individual will exhibit immediate hypersensitivity upon exposure to the allergen.
