Lancet:潜蚤病:一目了然的诊断——案例报道

2016-07-20 MedSci MedSci原创

22岁的日本女性去乌干达Manafwa区旅游两周后,右脚的大拇指出现持续性疼痛伴皮疹10天。她指出在学生户外活动期间都穿了袜子和鞋子,只在郊区宾馆附近穿着凉鞋未穿袜子。 体检发现:该患者右脚趾第一指甲处出现黄白色结节,直径5 mm,在结节的中央有黑色的斑点(图A)。由此,我们怀疑是3期潜蚤病,在局麻下切开结节,在结节中发现了大量的虫卵(图B),同时给予了破伤风抗毒素。

22岁的日本女性去乌干达Manafwa区旅游两周后,右脚的大拇指出现持续性疼痛伴皮疹10天。她指出在学生户外活动期间都穿了袜子和鞋子,只在郊区宾馆附近穿着凉鞋未穿袜子。

体检发现:该患者右脚趾第一指甲处出现黄白色结节,直径5 mm,在结节的中央有黑色的斑点(图A)。由此,我们怀疑是3期潜蚤病,在局麻下切开结节,在结节中发现了大量的虫卵(图B),同时给予了破伤风抗毒素。


立体显微镜下检测为穿皮潜蚤,体长0.5 mm,伴虫卵。7天后伤口损伤完全愈合,无再次感染征象(图C)。


潜蚤病是一种由雌性沙地跳蚤(穿皮跳蚤)导致的体表寄生疾病,主要分布于中南美洲,加勒比海及撒哈拉以南的非洲。主要的宿主是动物。一旦在人体寄生,小小的跳蚤可以在1-3周内增长到10mm,产下数百个卵。潜蚤病对流行区居民的健康是很大的威胁,会导致长期的活动障碍,制动,慢性疼痛,自行切除会导致威胁生命的二次细菌感染,如破伤风和血源性感染。虽然手术切除是一种有效的治疗方法,但局部使用二甲聚硅氧烷可减少潜在的不良反应。

潜蚤病是一种人畜共患的疾病,可划分为不同阶段,根据寄生的雌性沙地跳蚤的阶段不同,可产生不同的症状,使诊断变得困难。旅行者在流行区应注意穿着衣物和袜子。
