Souvenir from the Hamptons - a case of cutaneous larva migrans of six months' duration.

Cutaneous larva migrans is a distinctive serpiginous eruption caused by a reaction to burrowing hookworms. The infection is usually self-limited, normally lasting 2-8 weeks, but may persist for more than a year if misdiagnosed. Biopsies of the creeping eruption rarely reveal an organism. Thus, it is important for the infection to be recognized clinically, so that effective treatment may begin. We found topical thiabendazole to be fast and effective in treating this case of cutaneous larva migrans of six months' duration.
