Intradural chondrosarcoma is even rarer. &lt;b&gt;&lt;i&gt;Case:&lt;\/i&gt;&lt;\/b&gt; Here, we describe a case of dural chondrosarcoma with a radiation history for nasopharyngeal carcinoma and a radical prostatectomy for prostatic cancer 15 and 8 years earlier, respectively. A 67-year-old man presented with a 3-week memory disturbance and dysarthria. Computed tomography and magnetic resonance images of the brain revealed a dural-based mass in the left temporal area. Under the impression of a glioblastoma, a resection and an intraoperative squash cytology were done. A necrotic dirty background as well as bluish-to-pinkish myxoid stroma were characteristic; the nuclei of highly pleomorphic tumor cells were hyperchromatic to vesicular with an occasional ground-glass appearance. The cytoplasm was of an eosinophilic hyalinized condensed morphology with an occasional granular appearance. Histologically, the lobulated mass was composed of hypercellular lobules of well-differentiated chondrocytes intermixed with anaplastic pleomorphic cells and diagnosed as a conventional grade III chondrosarcoma. These cells were immunoreactive for D2-40, S-100 protein and vimentin. Brain invasion was also found. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; Albeit rare, dural-based chondrosarcomas should be considered in the differential diagnosis for meningeal tumors, especially in the case of previous radiation therapy.<\/jats:p>","DOI":"10.1159\/000380901","type":"journal-article","created":{"date-parts":[[2015,6,17]],"date-time":"2015-06-17T12:17:39Z","timestamp":1434543459000},"page":"219-224","source":"Crossref","is-referenced-by-count":6,"title":["Squash Cytology of a Dural-Based High-Grade Chondrosarcoma May Mimic That of Glioblastoma in the Central Nervous System"],"prefix":"10.1159","volume":"59","author":[{"given":"Sangho","family":"Lee","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Na Rae","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong Hae","family":"Chung","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gi-Taek","family":"Yee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyun Yee","family":"Cho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2015,5,19]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002\/dc.21506"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1111\/bpa.12012"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocn.2011.08.042"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1984.61.1.0174"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1186\/1742-6413-2-9"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.25734"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2303.1997.tb00573.x"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1159\/000325750"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1159\/000331840"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1159\/000357025"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1159\/000333752"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.22948"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1159\/000328496"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.3346\/jkms.2007.22.S.S149"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1159\/000353804"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e318194c566"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1159\/000326392"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1159\/000331161"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-3019(01)00329-9"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1080\/01913120390239999"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1259\/dmfr\/17575463"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1007\/s007010050177"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1007\/s11060-009-0089-9"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-200102000-00038"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197812)42:6<2744::AID-CNCR2820420633>3.0.CO;2-L"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1007\/BF01808691"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocn.2013.01.004"}],"container-title":["Acta Cytologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/380901","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/380901","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:48:06Z","timestamp":1745430486000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000380901"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":27,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2015,4,1]]},"published-print":{"date-parts":[[2015,6,11]]}},"URL":"https:\/\/doi.org\/10.1159\/000380901","archive":["Portico"],"relation":{},"ISSN":["0001-5547","1938-2650"],"issn-type":[{"value":"0001-5547","type":"print"},{"value":"1938-2650","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015]]}}}
