Two patients developed allergic contact dermatitis to 1% dyclonine hydrochloride gel, a nonprescription topical anesthetic widely marketed for the symptomatic treatment of herpes simplex labialis. Both patients mistakenly believed that the eruption was expanding herpes simplex labialis, which resulted in their more frequent application of the dyclonine hydrochloride and a delay in diagnosis. Dermatologists should recognize that 1% dyclonine hydrochloride gel can cause allergic contact dermatitis that can masquerade as widespread herpes simplex labialis.
两名患者对1%盐酸达克罗宁凝胶发生了过敏性接触性皮炎，该凝胶是一种非处方外用麻醉剂，广泛用于唇疱疹症状治疗。两名患者均错误地认为皮疹是正在扩散的唇疱疹，导致他们更频繁地使用盐酸达克罗宁，从而延误了诊断。皮肤科医生应认识到，1%盐酸达克罗宁凝胶可引起过敏性接触性皮炎，可能会伪装成广泛的唇疱疹。
