Lymphatic filariasis in India is caused mainly by two species of nematodes: <jats:italic>Wuchereria bancrofti<\/jats:italic> and <jats:italic>Brugia malayi<\/jats:italic>, which invade the human lymphatic system. We report two cases of superficial cystic lesions of the upper limb revealed on fine needle aspiration (FNA) to be clinically unsuspected filariasis. Despite similar aetiologies, both cases revealed variations in aspirate nature, smear morphology and peripheral blood findings. FNA provides definitive diagnosis and is an important tool for diagnosing soft tissue swellings owing to filariasis.<\/jats:p>","DOI":"10.1136\/bcr-2013-009677","type":"journal-article","created":{"date-parts":[[2013,5,18]],"date-time":"2013-05-18T00:32:42Z","timestamp":1368837162000},"page":"bcr2013009677","source":"Crossref","is-referenced-by-count":3,"title":["Role of fine needle aspiration cytology in diagnosing filarial arm cysts"],"prefix":"10.1136","volume":"2013","author":[{"given":"Nishi","family":"Tandon","sequence":"first","affiliation":[{"name":"Department of Pathology, Era Medical College and Hospital, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cherry","family":"Bansal","sequence":"additional","affiliation":[{"name":"Department of Pathology, CSMMU, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richa","family":"Sharma","sequence":"additional","affiliation":[{"name":"Department of Pathology, Era Medical College and Hospital, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sumaiya","family":"Irfan","sequence":"additional","affiliation":[{"name":"Department of Pathology, Era Medical College and Hospital, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2013,5,17]]},"reference":[{"key":"2025082803443251000_2013.may17_1.bcr2013009677.1","doi-asserted-by":"crossref","first-page":"186","DOI":"10.1159\/000327275","article-title":"Cytomorphology of filariasis revisited.
