This syndrome is justified by the homology between serum albumins from cat and pork. Evidence suggests that a primary sensitization to cat serum albumin Fel d 2 occurs, followed by allergic reactions after ingestion of pork meat containing serum albumin Sus s 1. Due to homology between other mammalian serum albumins, reactions with other meats can also be present. We report a well-documented case report of a patient with cat-pork syndrome, with initial mild and non-specific manifestations to well-cooked pork that were overlooked. Component resolved diagnosis was essential to establish the diagnosis, which confirmed the involvement of Fed 2 and Sus s 1, but less relevant in helping to define avoidance diets, since the sensitization profile was not in accordance with clinical manifestations. 2025-10-24T10:21:51Z 2025-10-24T10:21:51Z 2023-01-26T10:19:14Z 2023-01-26T10:19:14Z 2022-05 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://hdl.handle.net/11351/8918 Acta Médica Portuguesa;35(5) https://doi.org/10.20344/amp.15483 Attribution-NonCommercial 4.0 International http://creativecommons.org/licenses/by-nc/4.0/ info:eu-repo/semantics/openAccess Ordem dos Médicos Scientia
