Background: Bancroftian filariasis is a tropical and sub-tropical disease caused by Wuchereria bancrofti and transmitted by the culex mosquitoes. The diagnosis of it is conventionally made by demonstrating microfilariae in the peripheral blood smear. Case Report: We hereby report an unusual case of bancroftian filariasis in an adult male presenting with a painless sub-cutaneous nodule on the antero-medial aspect of the right arm. Conclusion: Our aim is to highlight the chances of finding microfilariae in an unsuspected case at an unusual site.
