Potato contains multiple heat-labile proteins which can induce immediate hypersensitivity reactions. Rhino-conjunctivitis, asthma, contact urticaria and protein contact dermatitis have been described in association with potato exposure.
A patient with possible airborne facial dermatitis to potato is described.
A middle-aged atopic housewife with pre-existent atopic dermatitis suffered from rhino-conjunctivitis, asthma, and contact urticaria when pealing raw potatoes, but her main complaint was intense, treatment-resistant dermatitis of the face. The investigations showed a positive prick test, a positive patch test, and positive specific serum IgE to raw potato. Potato avoidance led not only to the resolution of the immediate symptoms, but also of the facial dermatitis, suggesting she had dermatitis due to this vegetable.
Potato may induce contact dermatitis with positive immediate and delayed hypersensitivity tests.
马铃薯含有多种热不稳定蛋白，可引发速发型超敏反应。已有报道称，接触马铃薯会引发鼻结膜炎、哮喘、接触性荨麻疹和蛋白质接触性皮炎。
描述一名可能因接触马铃薯而发生气源性面部皮炎的患者。
一名患有特应性皮炎的中年特应性家庭主妇，在削生马铃薯时出现鼻结膜炎、哮喘和接触性荨麻疹，但她的主要症状是面部严重且难治性皮炎。检查显示皮内试验阳性、斑贴试验阳性以及对生马铃薯的特异性血清IgE阳性。避免接触马铃薯不仅使速发症状得到缓解，面部皮炎也得以消退，这表明她的皮炎是由这种蔬菜引起的。
马铃薯可能诱发接触性皮炎，且速发型和迟发型超敏试验均呈阳性。
