Prevalence of plant contact dermatitis in retail florists varies with exposure, and the number of reports of contact allergy to cut tulips is rather small. Alpha-methylene-gamma-butyrolactone is better known as the cause of both Alstroemeria dermatitis in retail florists and tulip finger in wholesale floral workers who handle the bulbs. Our patient presented with prominent erythema, scaling, and peeling of the skin of the thumb, index, and middle fingers of his right hand. Results of a patch test to alpha-methylene-gamma-butyrolactone were strongly positive, and the patient determined that the exposure had occurred when he stripped leaves from the tulip stems to arrange cut flowers. Other natural sources of the antigen include Alstroemeria; Bomarea; Dioscorea hispida; Erythronium; Gagea; Fritillaria; and at least one species of onion, Allium triquetrum.
零售花店中植物接触性皮炎的患病率因接触情况而异，对切花郁金香接触过敏的报告数量相当少。α-亚甲基-γ-丁内酯是零售花店中六出花皮炎以及处理球茎的批发花卉工人患郁金香手指病的更为人熟知的病因。我们的患者右手拇指、示指和中指皮肤出现明显红斑、脱屑和脱皮。对α-亚甲基-γ-丁内酯的斑贴试验结果呈强阳性，患者认定接触是在他为插花而剥去郁金香茎上的叶子时发生的。该抗原的其他天然来源包括六出花；竹叶吊钟；大薯；猪牙花；顶冰花；贝母；以及至少一种葱属植物，三棱葱。
