Pigmentation secondary to minocycline ingestion is an uncommon adverse event affecting 3.7-14.8% of treated individuals for which few effective therapies are available. Three patterns of minocycline pigmentation have a characteristic clinical and histological appearance. The pigment composition in each variety is different and occurs at varying skin depths. Accordingly, a tailored approach according to the type of minocycline pigmentation is crucial for treatment success. The purpose of this intervention was to evaluate the efficacy of non-ablative fractional photothermolysis in combination with the Q-switched alexandrite laser for the treatment of type I minocycline pigmentation on the face. A patient with type I minocycline pigmentation was treated with non-ablative 1550-nm fractional photothermolysis followed immediately by 755-nm Q-switched alexandrite laser and then observed clinically to determine the outcome of this modality. The patient was seen in clinic 1 month later following her single treatment session and 100% clearance of all blue facial pigment was observed. Non-ablative fractional photothermolysis in combination with the 755-nm Q-switched alexandrite laser should be considered for treatment of type I minocycline pigmentation.
米诺环素摄入引起的色素沉着是一种罕见的不良事件,在接受治疗的个体中发生率为3.7%-14.8%,针对此情况几乎没有有效的治疗方法。米诺环素色素沉着有三种类型,具有特征性的临床和组织学表现。每种类型的色素组成不同,且发生在不同的皮肤深度。因此,根据米诺环素色素沉着的类型采取针对性方法对于治疗成功至关重要。本干预措施的目的是评估非剥脱性分次光热解联合调Q紫翠宝石激光治疗面部I型米诺环素色素沉着的疗效。一名I型米诺环素色素沉着患者先接受非剥脱性1550nm分次光热解治疗,随后立即接受755nm调Q紫翠宝石激光治疗,然后进行临床观察以确定这种治疗方式的效果。单次治疗后1个月,该患者前来门诊复查,面部所有蓝色色素沉着均100%清除。对于I型米诺环素色素沉着的治疗,应考虑非剥脱性分次光热解联合755nm调Q紫翠宝石激光。
