Abstract：
Dermatological disorders are among the most common complaints of patients seeking medical assistance after returning from trips to tropical countries. Among exotic dermatoses, one of the frequently encountered diagnoses is Cutaneous Larva Migrans (CLM), primarily caused by the nematodes Ancylostoma braziliense and A. caninum. Cats and dogs, which serve as the definitive hosts for these nematodes, excrete with their stool parasite eggs into the environment, where they transform into larvae. Human infection occurs through the invasive form of the larvae, which penetrate the skin, causing itching and the characteristic serpiginous, slightly raised, and enlarging lesion at the site of invasion. Diagnosis is made based on the highly characteristic clinical presentation, although in non-endemic countries, diagnostic errors and delays in initiating effective causal treatment are relatively common. Effective therapy includes oral albendazole and ivermectin. Prevention of CLM involves avoiding skin contact with potentially contaminated soil by wearing shoes and using towels and mats on the beach. Due to the high interest in travel and the risk of importing exotic diseases, it is important to promote knowledge of tropical medicine among healthcare professionals as well as the travellers.
摘要：
皮肤病是患者从热带国家旅行返回后寻求医疗救助的最常见投诉之一。在异国情调的皮肤病中，经常遇到的诊断之一是皮肤幼虫偏头痛（CLM），主要由线虫巴西Ancylostoma和A.caninum引起。猫和狗，它们是这些线虫的最终宿主，随着它们的粪便寄生虫卵排泄到环境中，在那里它们转化为幼虫。人类感染是通过幼虫的侵入形式发生的，穿透皮肤，引起瘙痒和特征性的血清色素，稍微抬起,并扩大浸润部位的病变。诊断是基于高度特征性的临床表现，尽管在非流行国家，诊断错误和延迟启动有效的因果治疗是相对常见的。有效的治疗包括口服阿苯达唑和伊维菌素。预防CLM包括通过穿鞋和在海滩上使用毛巾和垫子来避免皮肤与潜在污染的土壤接触。由于人们对旅行的高度兴趣和输入外来疾病的风险，重要的是在医疗保健专业人员和旅行者中推广热带医学知识。
