Dirofilaria genus are the most commonly recognised zoonotic filarial infection.The worms are introduced into humans by the bites of mosquitoes containing third-stage larva.Pathologic examination of affected tissue reveals a localized foreign body reaction around a dead or dying parasite. The lesion consists of granulomas with eosinophils, neutrophils, and tissue necrosis.Definitive diagnosis and cure depend on surgical excision and identification of the nematode within the surrounding granulomatous response. Management is by surgical excision.
