- Abstract
Bishop's weed (Ammi majus) has been known to induce toxic phytophotodermatitis. We now describe IgE-mediated rhinitis and contact urticaria caused by exposure to bishop's weed in a 31-year-old atopic female florist. A skin prick-prick test with bishop's weed flowers gave an 8-mm wheal, and the bishop's weed-specific IgE level in the patient's serum was 9.7 PRU/ml (RAST class 3). In an immunoblotting experiment with the patient's serum, nine IgE-binding protein bands with the molecular weights 19, 34, 39–41 (doublet), 52–61 (doublet), and >67 (triplet) kDa were detected in bishop's weed extract. The patient became symptomless after she had ceased to work as a florist.
