Apart from profoundly disabling and disfiguring major clinical manifestations\u2014lymphoedema, elephantiasis and hydrocoele\u2014asymptomatic microfilaremia is common in endemic areas. Despite this, it is very rare to detect microfilariae in body fluids or aspirates. As per the literature search, this is the third case documenting incidental detection of microfilariae with metastatic deposits in the liver aspirate. Here, a 35-year-old man underwent image-guided fine-needle aspiration cytology of liver nodule. Liver aspirate cytology revealed poorly differentiated mucin-secreting metastatic carcinoma and coincidental presence of microfilariae of <jats:italic>W. bancrofti<\/jats:italic>. Recently, microfilaria has frequently been found to be associated with the debilitated, immunocompromised condition and various neoplasm\/cancer\/malignancy. Hence, meticulous investigation should be undertaken to search for hidden pathology, whenever microfilariae are detected; and to deeply scrutinise aspirates for such parasites always, especially in endemic regions.<\/jats:p>","DOI":"10.1136\/bcr-2019-231618","type":"journal-article","created":{"date-parts":[[2019,10,23]],"date-time":"2019-10-23T15:36:09Z","timestamp":1571844969000},"page":"e231618","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Rare association of microfilaria with poorly differentiated mucin-secreting metastatic carcinoma in liver aspirate cytology"],"prefix":"10.1136","volume":"12","author":[{"given":"Renuka","family":"Gahine","sequence":"first","affiliation":[{"name":"Pathology, Pandit Jawaharlal Nehru Memorial Government Medical College, Raipur, Chhattisgarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aditi","family":"Das","sequence":"additional","affiliation":[{"name":"Pathology, Pandit Jawaharlal Nehru Memorial Government Medical College, Raipur, Chhattisgarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vishal Kumar","family":"Jain","sequence":"additional","affiliation":[{"name":"Radiodiagnosis, Pandit Jawaharlal Nehru Memorial Government Medical College, Raipur, Chhattisgarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Apurva","family":"Agrawal","sequence":"additional","affiliation":[{"name":"Pathology, Pandit Jawaharlal Nehru Memorial Government Medical College, Raipur, Chhattisgarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,10,23]]},"reference":[{"key":"2025082713220547000_12.10.e231618.1","doi-asserted-by":"crossref","DOI":"10.1371\/journal.pntd.0003319","article-title":"Progress and impact of 13 years of the global programme to eliminate lymphatic filariasis on reducing the burden of filarial disease","volume":"8","author":"Ramaiah","year":"2014","journal-title":"PLoS Negl Trop Dis"},{"key":"2025082713220547000_12.10.e231618.2","doi-asserted-by":"crossref","first-page":"358","DOI":"10.1016\/S1473-3099(16)30544-8","article-title":"Global elimination of lymphatic filariasis","volume":"17","author":"Ndeffo-Mbah","year":"2017","journal-title":"Lancet Infect Dis"},{"key":"2025082713220547000_12.10.e231618.3","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2017-221845","article-title":"Bilateral breast filariasis mimicking inflammatory breast carcinoma","volume":"13","author":"Das","year":"2017","journal-title":"BMJ Case Rep"},{"key":"2025082713220547000_12.10.e231618.4","doi-asserted-by":"crossref","DOI":"10.5812\/iranjradiol.17991","article-title":"Breast filariasis diagnosed by real time sonographic imaging: a case report","volume":"13","author":"Sherwani","year":"2016","journal-title":"Iran J Radiol"},{"key":"2025082713220547000_12.10.e231618.5","doi-asserted-by":"crossref","first-page":"776","DOI":"10.1159\/000326996","article-title":"Microfilariae in association with other diseases.
