We report the case of a 17-year-old boy who experienced 4 episodes of exercise-induced anaphylactic reaction after ingestion of lentil and 2 episodes of anaphylaxis following ingestion of chickpea. His medical history revealed that he had allergic rhinitis with positive results after skin prick tests (SPT) with mites. His SPTs and specific immunoglobulin E antibody testing with lentil and chickpea were positive. Oral
challenge with chickpea was not performed due to patient refusal. Treadmill exercise challenge tests in the fasting state and 1 hour after a meal not containing lentil were negative. However, an exercise challenge test 1 hour after intake of lentil soup resulted in pruritus of the hands, forearms, shoulders, and back, urticarial lesions on the face and shoulders, mild angioedema of the lips, and mild hoarseness and
cough. To our knowledge, this is the first case of food-dependent exercise-induced anaphylaxis due to lentil.

Key words: Food-dependent exercise-induced anaphylaxis. Lentil. Anaphylaxis. Chickpea.
