Description

<p>　Mango fruit ( Mangifera indica ) belongs to the family Anacardicae and is well known to cause allergic contact dermatitis. However, type 1 hypersensitivity reactions, such as urticaria or anaphylaxis, are rare. Here, we report a case of anaphylaxis associated with ingestion of commercially available mango jelly. A 43-year-old woman first experienced anaphylaxis of unknown cause 6 or 7 years ago. Since then the patient experienced anaphylaxis several times. In July 2014, she ate a mango jelly and had relatively hard work at a nursery school. Forty minutes after the ingestion of mango jelly she developed anaphylaxis exhibiting cough, dyspnea, pruritic erythema and edematous swelling on her face, neck, hands and feet. Skin prick tests with mango jelly, fresh mango fruit, and fresh burdock demonstrated positive results. Specific IgE against mango and mugwort was 0.44 UA/ml (class 1) and 18.30 UA/ml (class 4) , respectively. Although the specific allergen component was undetectable, a heat-resistant antigen was suggested. It is possible that the patient's anaphylaxis was exercise-induced, as she developed symptoms following physical labor.</p>
