Case History
We present a case of a 24-years-old woman with atopic dermatitis, eosinophilic allergic asthma and cat allergy with previously history of severe anaphylaxis to walnut and almond (sensitization to storage proteins). The patient also has a history of bronchospasm with (non-occupational) airborne exposure to trace amounts of almond.
The patient was evaluated for anaphylaxis to a piece of dark chocolate. She developed ocular, nasal, oral and pharyngeal pruritus, lip angioedema, sneezing, rhinorrhea and intense abdominal pain within 5 minutes of ingestion. Her symptoms resolved after treatment with IM epinephrine in an emergency department. She had previously tolerated cocoa.
