24岁女性,左肩皮疹伴瘙痒5天。2周前在皮疹区域临时纹了一朵花,诊断为什么?


答案:黑色指甲花纹身导致的过敏性接触性皮炎。

讨论:

过敏性接触性皮炎是一种IV型超敏反应。指甲花染料是一种天然产品来源于植物Lawsonia inermis。指甲花醌是天然色素成分,能产生浅棕色颜色。然而,黑色指甲花染料不是自然的,在指甲花醌分子基础上添加了对苯二胺(PPD)。黑色指甲花染料是一个众所周知的过敏反应原因,大约使用后48h-10d起病,包括湿疹、永久性疤痕等。

该患者对PPD敏感,该物质常见于黑色染发剂,纺织染料和打印机墨水。为防止以后任何的进一步的严重反应,她应该远离含PPD的物质。最初对她采用了局部氢化可的松治疗方案,但是效果不佳,所以咨询了皮肤科医生,使用了效力更高的类固醇局部治疗一周。炎症反应虽然得到控制,但是皮疹区遗留炎症后色素沉着,需要好几个月的时间才能消退。

对于该疾病,早期使用有效的类固醇局部治疗是至关重要,可避免长期色素沉着和疤痕形成。

Lung Cancer:皮疹可能预示抗EGFR治疗肺癌有效

意大利肿瘤学家Petrelli Fausto博士等人研究发现,采用酪氨酸激酶抑制剂厄洛替尼或吉非替尼治疗非小细胞肺癌(NSCLC)时,发生皮疹可能是个好兆头。这项研究发表在《肺癌》(Lung Cancer)杂志7月16日在线版上。 皮肤反应(尤其是丘疹脓疱皮疹)是抗表皮生长因子受体(EGFR)治疗的最常见不良反应,原因是表皮基底层和基底上层中的未分化和增殖性角质细胞中有EGFR表达。一旦发生皮疹
