[Dirofilariasis, an unknown parasitosis. One case observed in Paris (author's transl)].

In France, dirofilariasis D. tenuis are rare (less than ten cases were recorded). They manifest themselves by subcutaneous nodules. The fact that sometimes important inflammatory signs exist, could being one to diagnose an infectious etiology. Diagnosis may be made when the nodule is in the periorbital region if the patient comes back from endemic area and specially if he noted a migration of the parasite. It is hardly possible to count on the laboratory exams and it is the biopsy that will prove the existence of the parasite and will assure the cure.
