We present the case of a 33-year-old nonatopic woman with multiple episodes of anaphylaxis after ingestion of different fruits. The fruits implicated were apple, banana and lychee: all of which belong to different and botanically disparate plant families. The reaction to apple and banana was confirmed by prick testing. There was no history of allergy to other agents that are known to have cross reactions with fruits, viz. latex or pollen. As such patients often do not present to dermatologists, we wish to highlight the rare but potentially fatal clinical entity of type I allergy to fruits without concomitant allergy to other common airborne/contact allergens. We also discuss the possible explanation of type I reaction to apparently unrelated fruits and the allergens involved in such reactions.
我们报告了一例33岁的非特应性女性病例，该患者在摄入不同水果后多次发生过敏反应。涉及的水果有苹果、香蕉和荔枝：它们均属于不同的、植物学上差异很大的植物科。对苹果和香蕉的反应通过点刺试验得到证实。患者没有对其他已知与水果有交叉反应的物质（即乳胶或花粉）过敏的病史。由于这类患者通常不会去皮肤科就诊，我们希望强调这种罕见但可能致命的临床实体——对水果的I型过敏，且不伴有对其他常见空气传播/接触性过敏原的过敏。我们还讨论了对明显不相关的水果发生I型反应的可能解释以及此类反应中涉及的过敏原。
