Severe angioedema caused by banana allergy under tacrolimus immunosuppression.

Occurrences of allergic reactions induced by various foods have been reported in pediatric liver graft recipients receiving tacrolimus immunosuppression. We describe herein a female infant, who was admitted to our hospital with life-threatening angioedema because of banana hypersensitivity, 8 months after orthotopic liver transplantation. Food allergies should be screened in all tacrolimus-immunosuppressed pediatric liver recipients who show suggestive clinical symptoms. Banana must be added to allergen batteries during etiologic investigations. Cyclosporine represents an option for drug conversion to prevent organ rejection.
