Dirofilariasis due to Dirofilaria repens is a rare anthropozoonotic disease, with dogs and cats being the definite hosts for this parasite. This worm is transmitted by various species of mosquitoes and usually presents as a subcutaneous nodule. Human cases have been reported from all around the Mediterranean, Eastern Europe, and Central and Southern Asia. In the present case involving a 28-year-old patient of Tunisian origin, infection manifested as a nodule in the left epididymis. In the context of increasing international travel and migration, dirofilariasis is a diagnosis that should be kept in mind when treating patients who have spent some time in endemic areas and present with unclear subcutaneous or scrotal nodules.

Dirofilariasis is a globally significant emerging-zoonotic-disease caused by nematode parasites belonging to the genus Dirofilaria (Rhabditida: Onchocercidae) and is transmitted by mosquitoes (Diptera: Culicidae) of the Culicidae family. A recent study on molecular prevalence of Dirofilaria sp. "hongkongensis" To, 2012 (nomen nudum) among the dog population in Kerala indicated a high infection rate.

Background: Dirofilaria immitis and D. repens are mosquito-borne filaroids that primarily infect dogs but also cats. Diagnosing feline dirofilariosis is challenging because of the low parasitic burdens and transient or absent microfilaremia.

Heartworm infection caused by Dirofilaria immitis induces a devastating disease that greatly affects the global canine population. The mechanism leading to heartworm pathology has been attributed to be mostly by mechanical damage of the worm to the dog´s vascular system and immune-mediated, but the latter processes are not completely understood. Autoantibodies targeting host molecules such as lipids and nucleic acids have been described with pathological roles during malaria and COVID-19 and mediating anemia and thrombocytopenia.
