Filariasis continues to be one of the endemic problems worldwide with 40% of the cases in India. We report a case of lymphatic filariasis in a 3-year-old girl who presented with a non-tender swelling over left inguinal region. Blood sample showed eosinophilia while the excision biopsy was diagnostic of filarial worm. Patient responded well with oral diethylcarbamazine. High index of suspicion of filariasis is indicated when dealing with a swelling of unknown cause even if it is not from an endemic area.
