Worrisome metaplastic changes may occur in WT. Their interpretation as mucoepidermoid carcinoma represents a diagnostic pitfall. Moreover, WT and mucoepidermoid carcinoma may coexist, making this distinction difficult. So it is worthwhile to report unusual WT features. We describe a WT with signet-ring cells (SRCs). &lt;b&gt;&lt;i&gt;Case:&lt;\/i&gt;&lt;\/b&gt; A 61-year-old male presenting with a 3.6-cm right parotid gland mass underwent FNA with rapid on-site evaluation. DiffQuik-stained smears showed groups of oncocytic cells with abundant granular cytoplasm in a background rich with debris, foamy macrophages and lymphoid cells. SRCs were observed on Papanicolaou-stained smears prepared from a second pass. A WT with SRC features was diagnosed. Histology revealed a WT with post-FNA infarctual changes. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; To avoid false-positive diagnoses, the cytopathologist should be aware that SRC features may occur in WT. The concomitant presence of oncocytes and SRCs is useful to correctly diagnose this unusual WT variant.<\/jats:p>","DOI":"10.1159\/000348248","type":"journal-article","created":{"date-parts":[[2013,4,25]],"date-time":"2013-04-25T08:57:04Z","timestamp":1366880224000},"page":"309-312","source":"Crossref","is-referenced-by-count":1,"title":["Warthin Tumor with Signet-Ring Cell Features as a Pitfall in Salivary Gland Cytopathology"],"prefix":"10.1159","volume":"57","author":[{"given":"Claudio","family":"Bellevicine","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonino","family":"Iaccarino","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Umberto","family":"Malapelle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giancarlo","family":"Troncone","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2013,4,25]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002%2Fcncr.11207"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1365-2303.2002.00415.x"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1002%2Fdc.2840070311"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1002%2Fdc.21267"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1365-2303.2009.00667.x"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1053%2Fcrad.2001.0865"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.humpath.2008.07.016"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097%2F00000478-200311000-00004"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.humpath.2011.04.025"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016%2FS0344-0338%2899%2980068-5"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1440-1827.1998.tb03961.x"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1365-2559.2001.01144.x"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1002%2F%28SICI%291097-0142%2819970715%2980%3A2%3C277%3A%3AAID-CNCR16%3E3.0.CO%3B2-R"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1309%2FRL5H-VC5D-9WE2-X71H"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1365-2559.2003.01638.x"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1365-2559.1999.035005432.x"}],"container-title":["Acta Cytologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/348248","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/348248","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:54:39Z","timestamp":1745434479000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000348248"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":16,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2013,6,1]]},"published-print":{"date-parts":[[2013,5,14]]}},"URL":"https:\/\/doi.org\/10.1159\/000348248","archive":["Portico"],"relation":{},"ISSN":["0001-5547","1938-2650"],"issn-type":[{"type":"print","value":"0001-5547"},{"type":"electronic","value":"1938-2650"}],"subject":[],"published":{"date-parts":[[2013]]}}}
