We present the case of a 72-year-old woman observed for dermatitis on the legs followed by apperance of erythema on the eyelids. She had a past history of peripheral venous insufficiency and had been using self home-made Aloe vera juice over the legs for relief from pain. Patch tests showed positive reactions to the leaf of Aloe, the macerated Aloe jelly, and nickel sulfate. Although most manufacturers process Aloe products avoiding its irritant extracts, and probably as a consequence reports of allergic reactions are rare, one must remember that the growing popularity on the use of Aloe products may stimulate its use 'as is' by the patients. Furthermore, it is important to specifically ask patients about the use of these products, because they consider it as innocuous and thus would not spontaneously provide such information.
我们报告一例72岁女性病例，该患者最初因腿部皮炎就诊，随后眼睑出现红斑。她有外周静脉功能不全的病史，一直在腿部使用自制的芦荟汁以缓解疼痛。斑贴试验显示对芦荟叶、芦荟凝胶浸软物和硫酸镍呈阳性反应。尽管大多数制造商在加工芦荟产品时会去除其刺激性提取物，因此过敏反应的报告可能很少，但必须记住，芦荟产品使用的日益普及可能会促使患者直接使用。此外，特别询问患者是否使用这些产品很重要，因为他们认为这些产品无害，因此不会主动提供此类信息。
