Cutaneous Larva Migrans as a frequent problem in travellers.

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.
