MALT lymphomas were divided into 44 common MALT and 7 MALT lymphomas with extreme plasmacytic differentiation (MALT-EPCD). &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; (1) Small- to medium-sized cells displaying irregularly shaped nuclei with prominent nucleoli (ISN-PN) were neoplastic cells. (2) In the case of a frequency of plasma cells (PC) below 15%, the accuracy rate for distinguishing common MALT from HT was 97% for ISN-PN cell frequencies above 20% in combination with the presence of lymphoepithelial lesion clusters (LELC) and mountain range-like clusters (MRLC). The frequency of large-sized cells was below 15% in common MALT. (3) In the case of a frequency of PC above 15%, cases with a sum of PC and ISN-PN cells above 30% were MALT-EPCD. (4) MRLC were cell clusters derived from regions of follicular colonization, and LELC were cell clusters from lymphoepithelial lesions of MALT lymphomas. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; Useful cytological criteria for the diagnosis of thyroid primary MALT lymphoma, such as neoplastic cells and cell clusters, were defined.<\/jats:p>","DOI":"10.1159\/000369443","type":"journal-article","created":{"date-parts":[[2014,12,17]],"date-time":"2014-12-17T07:38:50Z","timestamp":1418801930000},"page":"26-36","source":"Crossref","is-referenced-by-count":13,"title":["Cytological Findings for the Diagnosis of Primary Thyroid Mucosa-Associated Lymphoid Tissue Lymphoma by Fine Needle Aspiration"],"prefix":"10.1159","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4723-8919","authenticated-orcid":false,"given":"Sadayuki","family":"Kaba","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitsuyoshi","family":"Hirokawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miyoko","family":"Higuchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0827-1580","authenticated-orcid":false,"given":"Ayana","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaru","family":"Kojima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akira","family":"Miyauchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2014,12,17]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19831015)52:8<1410::AID-CNCR2820520813>3.0.CO;2-3"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdf146"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.5795\/jjscc.52.428"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.5795\/jjscc.52.507"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1002\/dc.2840030314"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1002\/dc.2840070213"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1002\/dc.2840090607"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.5795\/jjscc.36.115"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.5795\/jjscc.36.613"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2303.2001.00338.x"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.5795\/jjscc.41.327"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1159\/000326571"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1186\/1742-6413-2-21"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.2009.071423"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1002\/dc.21106"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2303.2010.00831.x"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-195008000-00018"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1136\/pgmj.66.776.477"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1089\/thy.1994.4.65"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0339(200011)23:5<354::AID-DC15>3.0.CO;2-7"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1002\/dc.20086"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1016\/j.anndiagpath.2007.07.003"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1309\/5EL22BH45PHUPM8P"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1002\/dc.23000"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.4061\/2010\/840469"}],"container-title":["Acta Cytologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/369443","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/369443","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:01:38Z","timestamp":1745431298000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000369443"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,12,17]]},"references-count":25,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2015,2,1]]},"published-print":{"date-parts":[[2015,4,17]]}},"URL":"https:\/\/doi.org\/10.1159\/000369443","archive":["Portico"],"relation":{},"ISSN":["0001-5547","1938-2650"],"issn-type":[{"value":"0001-5547","type":"print"},{"value":"1938-2650","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,12,17]]}}}
