L'allergie au tournesol et à son huile : rôles du contact,de l'ingestion et de l'inhalation

We report the case of a 5-years old girl with food allergy to sunflower oil. Sensitivity to sunflower oil and seeds was demonstrated by skin tests whereas assays of serum for sunflower-specific IgE were negative. An oral challenge test with 54 ml of sunflower oil was positive. The patient also reacted to cutaneous contact and inhalation of sunflower seeds. Depending on the route of contact –– skin contact, ingestion or inhalation –– sunflower oil and seeds can trigger symptoms such as urticaria, erythema, vomiting, dyspnea or fatigue.
