[Human dirofilariasis: a new French case of Dirofilaria repens].

Dirofilariosis is an endemic filarial parasitic disease in the Mediterranean basin, unfamiliar in France. Its incidence and geographic area are increasing due to global warming. Dogs and cats are the usual hosts, but humans may be accidentally infected. We reported the 91st case of French dirofilariosis, contracted in Camargue (South France) which appeared as a subcutaneous abdominal nodule. Ultrasound strongly guided the diagnosis by showing a linear structure moving in a fibrocystic structure. Surgical excision confirmed the diagnosis of species (Dirofilaria repens) and this remains the only curative treatment.
