[Autochthonous filaria in south-west France caused by Dirofilaria repens].

Background: Dirofilariasis is an autochthonous disease caused by Dirofilaria (Nochtiella) repens, a subcutaneous parasite of dogs and other carnivorous animals. Human infection leads to a self-limiting disease that generally presents clinically as a subcutaneous nodule. We describe a case occurring outside the classical endemic Mediterranean region.
