He was hospitalized due to lower extremities\u2019 paralysis. Computed tomography scan findings revealed multiple nodules of bilateral lungs, swollen mediastinal lymph nodes, and osteolysis of thoracic vertebrae. We performed spinal decompression and biopsy from vertebra. And, we finally diagnosed this case as metastases of mediastinal alveolar soft-part sarcoma which was removed 10 years ago. Alveolar soft-part sarcoma is rare tumor accounted for 0.5%\u20131.0% of soft tissue sarcoma that often occurs primarily in the lower extremities and trunk. It is difficult to distinguish between alveolar soft-part sarcoma and paraganglioma, renal cell carcinoma and granular cell tumor morphologically. Periodic acid\u2013Schiff stain and immunohistochemical staining of ASPL-TFE3 are useful in making a definitive diagnosis of alveolar soft-part sarcoma. This case is a rare case of alveolar soft-part sarcoma originated in the mediastinum with local recurrence and distant metastases 10 years after the initial surgery.<\/jats:p>","DOI":"10.1177\/2050313x17695473","type":"journal-article","created":{"date-parts":[[2017,2,24]],"date-time":"2017-02-24T02:16:18Z","timestamp":1487902578000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Alveolar soft-part sarcoma of the mediastinum: A case report"],"prefix":"10.1177","volume":"5","author":[{"given":"Yohei","family":"Kameda","sequence":"first","affiliation":[{"name":"Respiratory Disease Center, Yokohama City University Medical Center, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teppei","family":"Nishii","sequence":"additional","affiliation":[{"name":"Respiratory Disease Center, Yokohama City University Medical Center, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Tsuboi","sequence":"additional","affiliation":[{"name":"Respiratory Disease Center, Yokohama City University Medical Center, Yokohama, Japan"},{"name":"Division of Thoracic Surgery, National Cancer Center Hospital East, Kashiwa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiromasa","family":"Arai","sequence":"additional","affiliation":[{"name":"Respiratory Disease Center, Yokohama City University Medical Center, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenji","family":"Inui","sequence":"additional","affiliation":[{"name":"Respiratory Disease Center, Yokohama City University Medical Center, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeshi","family":"Kaneko","sequence":"additional","affiliation":[{"name":"Respiratory Disease Center, Yokohama City University Medical Center, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriko","family":"Kimura","sequence":"additional","affiliation":[{"name":"Pathology Division, Department of Clinical Research, National Hospital Organization Hakodate Hospital, Hakodate, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mitsuhide","family":"Naruse","sequence":"additional","affiliation":[{"name":"Division of Endocrinology, Metabolism and Hypertension, Kyoto Medical Center, Kyoto, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Munetaka","family":"Masuda","sequence":"additional","affiliation":[{"name":"Department of Surgery, Graduate School of Medicine, Yokohama City University, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,2,23]]},"reference":[{"key":"bibr1-2050313X17695473","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(20010201)91:3<585::AID-CNCR1038>3.0.CO;2-0"},{"key":"bibr2-2050313X17695473","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.1997.2690871.x"},{"key":"bibr3-2050313X17695473","doi-asserted-by":"publisher","DOI":"10.1159\/000071199"},{"key":"bibr4-2050313X17695473","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200306000-00005"},{"key":"bibr5-2050313X17695473","doi-asserted-by":"publisher","DOI":"10.5114\/pjp.2014.48195"},{"key":"bibr6-2050313X17695473","doi-asserted-by":"publisher","DOI":"10.1158\/1078-0432.CCR-08-2050"},{"key":"bibr7-2050313X17695473","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdq644"},{"key":"bibr8-2050313X17695473","doi-asserted-by":"publisher","DOI":"10.1159\/000450545"}],"container-title":["SAGE Open Medical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X17695473","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/2050313X17695473","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X17695473","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T00:33:34Z","timestamp":1777595614000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/2050313X17695473"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,1,1]]},"references-count":8,"alternative-id":["10.1177\/2050313X17695473"],"URL":"https:\/\/doi.org\/10.1177\/2050313x17695473","relation":{},"ISSN":["2050-313X","2050-313X"],"issn-type":[{"value":"2050-313X","type":"print"},{"value":"2050-313X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,1,1]]},"article-number":"2050313X17695473"}}
