Background We report a case of IgE-mediated hypersensitivity to lemon seed. We demonstrate for the first time a pattern of cross-sensitisation between seeds of citrus hybrid species from similar ancestral species origins. Case report Described is a case of a 26-year-old female with recurrent anaphylaxis on exposure to lemon seed with sensitisation shown on prick to prick testing. Prick to prick testing was also performed to a variety of citrus fruit seeds and edible foods from additional notable families of the Sapindale order. Conclusion In cases of unexplained or recurrent anaphylaxis in adult patients, citrus seed allergy should be considered.

柠檬籽过敏：案例介绍。

背景 我们报告了一例 IgE 介导的对柠檬种子过敏的病例。我们首次证明了来自相似祖先物种起源的柑橘杂交种种子之间的交叉敏感模式。病例报告 描述的是一名 26 岁女性，因接触柠檬种子而反复出现过敏反应，点对点测试显示过敏。还对来自 Sapindale 命令的其他著名家族的各种柑橘类水果种子和可食用食品进行了点对点测试。结论 成人患者出现不明原因或反复出现过敏反应时，应考虑柑橘类种子过敏。
