Rabbit anaphylaxis - An interesting case report

Rabbits are an unusual cause for allergic hypersensitivity; however, this domesticated animal must be considered in the differential diagnosis for symptoms ranging from rhinitis to anaphylaxis. We report an unusual case of allergic hypersensitivity to rabbits. This case involves a 6-year-old female who experienced anaphylaxis after oral ingestion of a rabbit that she had previously been sensitized to as a pet. This clinical scenario is an important one, as it alerts the clinician to the importance of recognizing rabbits as a potential source for allergens. Although it is extremely uncommon to have clinical manifestations from domesticated rabbits, it remains one of the possibilities for allergic disease, and a proper and thorough history should always be taken in an effort to shed light on the diagnosis. This case also demonstrates that aerosolized antigens crossreacting with antigen ingestion must always be included in the differential diagnosis of atopic disease.
