Cutaneous larva migrans is a self-limited cutaneous eruption caused by larva of roundworms that do not normally parasitize humans. Ankylostoma brazielensis, the dog and cat hookworm, is the most common agent. The disease is found in tropical and subtropical regions and may be seen in travelers from these regions. We report a case of a 37-year-old Iranian man who had cutaneous larva migrans after traveling to Mexico. The patient was successfully treated with oral thiabendazole.
