The alpha-Gal syndrome is a tick-associated and emerging IgE-mediated hypersensitivity reaction directed against the carbohydrate Gal alpha 1-3Gal beta 1-(3)4GlcNAc-R (alpha-Gal) epitope after red meat intake. Herein, we describe a clinical case of a 44-year-old French patient who suffered from recurrent anaphylactic reactions after mammalian meat consumption for five years before the final diagnosis of the alpha-Gal syndrome was established in 2018. The patient also reported multiple tick bites prior to symptom onset. This unique type of allergy has increasingly been reported across the world, but it is still unknown in many European countries. Therefore, the present clinical case should increase awareness among primary care practitioners and further improve the early diagnosis of the alpha-Gal syndrome in affected individuals.
