Abstract
Food toxicity is a common cause of morbidity worldwide. Presentations of food toxicity can take diverse forms, depending on the underlying mechanisms. Scombroid is one of the most frequent forms of food toxicity; however, its exact incidence remains unknown owing to similarities with other pathologies. Scombroid is a type of food poisoning caused by the ectopic consumption of histamine that mimics angioedema. Here, we present the case of a 36-year-old male patient who presented to the emergency department (ED) after consuming tuna, with a clinical picture of generalized erythema accompanied by pruritus and gastrointestinal symptoms, without dyspnea, lip or tongue edema, and no known allergies. The patient responded well to an H1 antihistamine, with no relevant analytical changes or hemodynamic stability during observation in the ED.
