NEJM:瘤蝇幼虫病-案例报道

2017-03-30 xing.T MedSci原创

该嗜人瘤蝇(也被称为putzi蝇或皮肤蛆)是非洲热带所特有的。雌性嗜人瘤蝇在潮湿的衣服或土壤中产卵,在与皮肤短暂接触后,幼虫进入皮下组织(通常在背部、臀部或四肢后侧)。在感染最初阶段幼虫很容易消失。涂抹石蜡凝胶封闭入口可使幼虫重回到皮肤表面,在一些病例中,手术摘除是必要的。

患者为一名46岁的女性,因右侧手臂疼痛和肿胀10天而到急诊就诊。她最近刚从科特迪瓦回到了英国。

检查发现不同部位存在溃疡伴右侧肘部远端环形红斑。诊断为昆虫叮咬引起的蜂窝组织炎,并用抗生素治疗。第二天,蜂窝组织炎出现恶化,并且可以明显见到振荡运动的幼虫(如图A)。经局部麻醉后,手术取出四条幼虫(如图B和图C)。寄生虫学检查证实为嗜人瘤蝇的幼虫。

幼虫取出后,患者手臂疼痛和肿胀迅速解决。
