Food Protein-Induced Enterocolitis Syndrome Due To Cuttlefish in A Child With Anaphylaxis To Crustaceans

Shellfish is defined as any edible marine invertebrate and refers to crustaceans and mollusks. crustaceans belong to the phylum arthropods. mollusks belong to the phylum mollusca. this report illustrates a rare case of a 6-year-old girl with challenge-proven acute food protein–induced enterocolitis syndrome (fpies) to cuttlefish (phylum mollusca, class cephalopoda), anaphylaxis to crustaceans (phylum arthropoda), and tolerance to other mollusks, including clams and mussels (phylum mollusca, class bivalvia). the association of ige-mediated food allergy and acute fpies seen in this case is rare. to our knowledge, this is the first case of fpies to cuttlefish reported in a child. this challenge highlights the need for further research into the allergens and mechanisms underpinning fpies at a molecular level, enabling a better understanding of cross-reactivity patterns and the development of diagnostic and predictive tests to assist in clinical practice.
