We present a case of this carcinoma that contained, in addition to a \u201ccommon\u201d morphology, scattered foci of yolk sac tumor differentiation. The tumor occurred in paranasal sinuses in a 44-year-old woman. Immunohistochemically, it was diffusely negative for INI1, whereas an expression of yolk sac tumor markers (\u03b1-fetoprotein, glypican-3, CDX2) was limited to the yolk sac tumor component. For comparison with the present case, we performed INI1 immunostaining on a series of 11 gonadal germ cell tumors with yolk sac tumor differentiation. All of these cases showed strong and diffuse expression of INI1, in contrast with the present sinonasal tumor. Our findings expand the morphologic spectrum of SMARCB1 (INI1) deficient sinonasal carcinoma. In addition, we show preliminarily that gonadal germ cell tumors with yolk sac tumor differentiation are not SMARCB1\/INI1-deficient.<\/jats:p>","DOI":"10.1177\/1066896917741549","type":"journal-article","created":{"date-parts":[[2017,11,23]],"date-time":"2017-11-23T03:39:44Z","timestamp":1511408384000},"page":"245-249","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":40,"title":["Sinonasal SMARCB1 (INI1) Deficient Carcinoma With Yolk Sac Tumor Differentiation: Report of a Case and Comparison With INI1 Expression in Gonadal Germ Cell Tumors"],"prefix":"10.1177","volume":"26","author":[{"given":"Michal","family":"Zamecnik","sequence":"first","affiliation":[{"name":"Department of Pathology, Agel Laboratories a.s, Novy Jicin, Czech Republic"},{"name":"Medirex Group Academy, Bratislava, Slovak Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiri","family":"Rychnovsky","sequence":"additional","affiliation":[{"name":"Department of Pathology, Agel Laboratories a.s, Novy Jicin, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jakub","family":"Syrovatka","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology \u2013 Head and Neck Surgery, Agel Hospital, Novy Jicin, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,11,23]]},"reference":[{"key":"bibr1-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0000000000000797"},{"key":"bibr2-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0000000000000236"},{"key":"bibr3-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0000000000000285"},{"key":"bibr4-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-016-0752-3"},{"key":"bibr5-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1002\/dc.23503"},{"key":"bibr6-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1007\/s00428-015-1853-1"},{"key":"bibr7-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(83)80004-5"},{"key":"bibr8-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19840515)53:10<2140::AID-CNCR2820531025>3.0.CO;2-Y"},{"key":"bibr9-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1111\/his.12373"},{"key":"bibr10-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1007\/s13277-012-0479-z"},{"key":"bibr11-1066896917741549","first-page":"198","volume":"110","author":"Manivel C","year":"1986","journal-title":"Arch Pathol Lab Med"},{"key":"bibr12-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1111\/apm.12409"},{"key":"bibr13-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1385\/JUP:11:2-3:161"},{"key":"bibr14-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(85)80137-4"},{"key":"bibr15-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1007\/s00428-002-0736-4"},{"key":"bibr16-1066896917741549","doi-asserted-by":"publisher","DOI":"10.5114\/pjp.2013.39331"},{"key":"bibr17-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1111\/his.13177"},{"key":"bibr18-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1016\/0165-4608(83)90125-5"},{"key":"bibr19-1066896917741549","doi-asserted-by":"publisher","DOI":"10.1016\/j.humpath.2016.08.002"}],"container-title":["International Journal of Surgical Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896917741549","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1066896917741549","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896917741549","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:21:54Z","timestamp":1777458114000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1066896917741549"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,11,23]]},"references-count":19,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2018,5]]}},"alternative-id":["10.1177\/1066896917741549"],"URL":"https:\/\/doi.org\/10.1177\/1066896917741549","relation":{},"ISSN":["1066-8969","1940-2465"],"issn-type":[{"value":"1066-8969","type":"print"},{"value":"1940-2465","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,11,23]]}}}
