Dans le Laboratoire de Parasitologie de la Faculté de Médecine Vétérinaire de l’Université de Bologna les auteurs ont observé, depuis 1971, 30 cas de dirofilariose humaine (sur 101 signalés en Italie) identifiés dans la presque totalité comme étant dus à Dirofilaria repens (Railliet et Henry, 1911) nématode parasite du chien relativement fréquent en Italie. De ces 30 cas, 23 étaient à localisation sous-cutanée, 4 sous-muqueux et 3 pulmonaires. La parasitose a été presque toujours méconnue cliniquement, étant interprétée comme une néoplasie bénigne ou maligne ou comme un corps étranger. Le parasite a pu être reconnu grâce à l’examen des coupes histologiques. Dans 3 cas on a pu énucléer du nodule l’helminthe entier. Les auteurs ont l’impression que la parasitose est beaucoup plus fréquente chez l’homme en Italie que ce qu’il apparaît dans la littérature scientifique : certains cas, pouvant guérir spontanément et d’autres n’étant pas diagnostiqués.
Abstract
Since 1971, at the Laboratory of Parasitology, Faculty of Veterinary Medicine, University of Bologna, 30 cases of human dirofilariasis were observed out of the 101 cases reported in Italy. The causative agent was identified in nearly all the cases as Dirofilaria repens (Nematoda, Filarioidea) a parasite relatively common in the dog in Italy. 23 cases were localized in the subcutaneous tissue, 4 in the submucosa and 3 in the lungs. In the majority of the cases the diagnosis had been misinterpreted, the lesions being first seen as malignant or benign tumours or foreign-body granuloma. The parasite was histologically recognized. In 3 cases the parasite could be extracted intact from the nodule. The authors believe that human dirofilariasis is more frequent than reported by the relevant scientific literature in that many cases are likely to recover spontaneously while others would remain undetected.
