Cutaneous larva migrans.

The case of cutaneous larva migrans presented here is typical for its mechanism and geographic location of infection, evolution of lesions, and prompt response to treatment. Except for pinworms, helminth infections are rarely thought of in emergency departments away from the areas where the parasites are especially prevalent. The several-day incubation period and modern-day ease of travel should place this illness on one's list of the differential diagnoses of pruritic lesions regardless of the location of practice. This case serves as a reminder that in a mobile society, diseases, as well as patients, can travel.
