We report the case of a 48-year-old patient suffered from asthma and conjunctivitis caused by an immediate type allergy to weeping fig (Ficus benjamina). By RAST inhibition test we could demonstrate that IgE antibodies react with allergens of fig; however our patient tolerated figs in oral provocation test. Sensitization to latex proteins reported to be cross reactive to Ficus species was not found. Ficus benjamina allergens represent relevant indoor allergens. A standardized allergen extract for skin testing is not yet available. Allergen specific IgE is mostly found in patients with strongly positive prick test results using the native sap of the tree. In 12 of 64 latex allergic patients we found simultaneous sensitization to weeping fig, so that cros-sensitization has to been considered in patients with IgE-mediated sensitization to latex.
我们报告了一例48岁患者，该患者因对垂叶榕（Ficus benjamina）速发型过敏而患有哮喘和结膜炎。通过放射变应原吸附抑制试验，我们能够证明IgE抗体与榕属植物的过敏原发生反应；然而，我们的患者在口服激发试验中耐受榕属植物。未发现对据报道与榕属植物有交叉反应的乳胶蛋白致敏。垂叶榕过敏原是重要的室内过敏原。目前尚无用于皮肤试验的标准化过敏原提取物。使用该树的天然汁液进行点刺试验结果呈强阳性的患者中，大多可检测到过敏原特异性IgE。在64例乳胶过敏患者中，有12例同时对垂叶榕致敏，因此对于IgE介导的乳胶致敏患者，必须考虑交叉致敏情况。
