The prevalence of sesame food allergy continues to increase worldwide. The diagnostic tools to confirm such allergy include skin prick tests, specific IgEs and food challenge. We report the case of a 7-year-old girl who presented recurrent episodes of wheezing and dyspnoea. After performing skin tests and evaluating specific IgEs we hypothesised an allergy to sesame. Our patient actually benefitted from avoiding any contact with sesame and sesame seeds. We confirmed our diagnosis through an inhalation food challenge. Further, by reviewing her personal history, we suspect inhalation was the mechanism in which the girl became sensitised to sesame.
