Topical corticosteroids are an emerging cause of allergic contact dermatitis in children that may often be missed. It is important to consider patch testing with corticosteroids to detect allergic contact dermatitis in patients with persistent or worsening of dermatitis despite topical corticoseroid treatment. However, delayed reactions (>7 days) to topical corticosteroids may occur, leading to false-negative reactions and misdiagnosis. Herein, we report a case of an 8-year-old girl who developed a positive reaction to budesonide on day 12 of patch testing.
外用糖皮质激素是儿童过敏性接触性皮炎的一个新出现的病因，常常可能被漏诊。对于那些尽管接受了外用糖皮质激素治疗但皮炎仍持续或加重的患者，考虑进行糖皮质激素斑贴试验以检测过敏性接触性皮炎很重要。然而，外用糖皮质激素可能会出现延迟反应（>7天），导致假阴性反应和误诊。在此，我们报告一例8岁女孩，其在斑贴试验第12天对布地奈德出现阳性反应。
