Abstract: Lymphatic filariasis, caused by Wuchereria bancrofti is an important parasitic disease included in the National vector-borne disease control programme in India to bring down the microfilariae carriage rate and disease prevalence in endemic zones in the country. Unplanned urbanization and frequent travel of people from non-endemic areas to endemic areas has increased the threat of this infection, even in non-endemic zones. We report a case of a 19 year old girl from Rajasthan (non-endemic state) who came with the complaint of cervical lymphadenopathy. Extensive follow-up of patient with various investigations such as CBC, urine complete, X-ray, CECT neck, Giemsa staining of PBF, FNAC of lymph node and AFB staining of sputum were carried out when a final diagnosis of lymphatic filariasis could be established by demonstrating live, motile microfilariae in EDTA blood sample collected in night hours. Also, Giemsa-stained PBF revealed sheathed microfilariae with cephalic space: breadth ratio of 1:1, regularly placed purple-coloured nuclei over the entire length and tail-tip free of nuclei.
