Resumo:
Introduction: Allergy to sunflower seed and oil is rare. Bird breeders and workers exposed to sunflower allergens are predisposed to sunflower allergy.
Case Report: The authors present the case of a 45-year-old female patient, admitted to the emergency department due to urticaria and angioedema that appeared 30 minutes after the patient ingested a wheat bread with sunflower butter. The emergency doctors gave her antihistamines and corticosteroids IV, and adrenaline IM, which resolved the symptoms. After that, she had returned to eat wheat bread, but no sunflower butter, without any clinical complaints. In the diagnostic work-up of allergy we found that skin prick tests were positive to sunflower seeds and sunflower butter and negative to nsLTP (Pru p3). The patient was advised to avoid sunflower seeds and sunflower butter and was provided with a written emergency plan. Despite this, the patient had two more episodes of urticaria shortly after eating seed bread and fried fish in sunflower oil.
Conclusion: The described case is interesting because sunflower oil allergy is extremely rare and it should raise our awareness for its possible allergenicity in patients allergic to sunflower seeds.
