[Cutaneous larva migrans: 34 outside cases]

Cutaneous larva migrans (CLM) is a frequent dermal disease in travelers, caused by larvae of nonhuman ancylostoma. We describe 34 outside cases of CLM diagnosed since January 1991 to June 2002. Nineteen male and female. Age: 35.7 years (20-60). The total number of CLM infestations was 73, 83.5% in feet. In five cases the cutaneous lesion was vesiculoampollous (14.7%). Ivermectin, utilized in 3 cases with a single dose of 12 mg, failed in one patient (33.3%). Thiabendazole was effective in 6 (85.7%) of 7 cases and 4 (57.1%) patients showed side effects. Albendazole at doses of 400 mg/ 12 hours/3 days was effective in 22 (84.6%) of 26 cases. Possibly it is advisable to use albendazole more than 3 days in order to prevent the failures (15.4%) as those in our series.
