We herein describe a case of allergy to lingonberry in a 25-year-old woman with a history of mite allergic rhinitis, but no food allergies. She entered a restaurant and then ate meatballs, baked potatoes and lingonberry jam. During the meal, itching wheals developed around her mouth. Symptoms were solved without treatment. The patient was not under any treatment on that time. Skin prick testing by prick-prick method with fresh lingonberry revealed mean wheal diameter of 5 mm and mean flare diameter of 20 mm (Figure 1a). Skin tests either with the foodstuffs involved in the episode or other berries showed no reaction. On her responsibility and against medical advice, she subsequently took a very little amount of lingonberry jam several days later. She immediately noticed more intense symptoms with intense itching on mouth, tongue and throat and wheals over her mouth. Symptoms were solved in an hour without treatment.
