[Cutaneous larva migrans, autochthonous in France. Apropos of a case]

Cutaneous larva migrans is rarely contracted in temperate countries.

When his house became flooded, he had to stand for a long period of time with mud up to the thigh. Some days later, he developed multiple erythematous, serpiginous pruritic tracts moving 1-2 cm per day over preexisting lesions of the right leg. Local and systemic treatment with thiabendazole led to rapid and definitive cure.

Cutaneous larva migrans results from the migration of hookworm larvae in the dead-end human host. It is mainly an imported disease and native cases in Europe as reported here are rare. This case demonstrates that the conditions leading to the development of cutaneous larva migrans are rarely found simultaneously in temperate zones.
