[Subcutaneous human dirofilariasis].
After a short review of the literature, starting from the last decades of the past century, the current classification of the Dirofilaria genus is shown with its two subgenera: D. immitis and D. nochtiella (repens, tenuis and ursi). The first case of subcutaneous and pulmonary dirofilariasis caused in Italy by D. repens is then shown as well as a research on dog populations in which D. immitis is prevalent. The fact that D. immitis has not yet been isolated in humans, in Italy, is probably due to D. repens vectors being more anthropophile. Finally, the latest cases of dirofilariasis from D. repens reported in Italy are taken into consideration along with the one isolated by the Authors, complete with illustrations. The case presented has been diagnosed on the basis of the histological examination carried out on a soft nodule detected in the right pectoral region; furthermore, eosinophilia and an elevated value PRIST were present.
