Primary Dirofilariasis is caused by a Zoonotic filarial nematode. It is transmitted to humans by Culex, Aedes, or Anopheles mosquitoes, which ingest blood-containing microfilaria from affected dogs, cats, or raccoons. Chest wall tumors are uncommon lesions that originate from blood vessels, nerves, bone, cartilage, or fat. We report a case of Human Dirofilariasis due to D. Repens occurring in the chest wall in a 32 year old male. Clinical diagnosis of benign chest wall tumor was considered and it was excised. Histopathological examination confirmed it as Dirofilaria repens. On regular follow up he is doing fine.
