It is an indolent neoplasm with good prognosis. In approximately 6% of STs, sarcomatous dedifferentiation may occur, portending an aggressive behaviour and representing a significant diagnostic challenge that can lead to its misdiagnosis. Herein, we report the clinicopathological features of a patient with a sarcomatoid spermatocytic tumor, initially diagnosed as mixed germ cell tumour, who was referred to our institution with lung metastases mainly composed of rhabdomyosarcomatous elements. This case report illustrates the importance of recognizing this entity for adequate management of these patients.<\/jats:p>","DOI":"10.1177\/10668969221122995","type":"journal-article","created":{"date-parts":[[2022,9,21]],"date-time":"2022-09-21T03:54:13Z","timestamp":1663732453000},"page":"728-733","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Sarcomatoid Spermatocytic Tumour: Report of a Rare Case and Literature Review"],"prefix":"10.1177","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5194-2784","authenticated-orcid":false,"given":"Andr\u00e9 Fontes","family":"Dias","sequence":"first","affiliation":[{"name":"NOVA Medical School | Faculdade de Ci\u00eancias M\u00e9dicas da Universidade NOVA de Lisboa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eug\u00e9nia","family":"Dvindenko","sequence":"additional","affiliation":[{"name":"Servi\u00e7o de Anatomia Patol\u00f3gica do Instituto Portugu\u00eas de Oncologia de Lisboa Francisco Gentil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Filipa","family":"Santos","sequence":"additional","affiliation":[{"name":"Servi\u00e7o de Anatomia Patol\u00f3gica do Instituto Portugu\u00eas de Oncologia de Lisboa Francisco Gentil"},{"name":"Faculdade de Medicina de Lisboa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafael","family":"Cabrera","sequence":"additional","affiliation":[{"name":"Servi\u00e7o de Anatomia Patol\u00f3gica do Instituto Portugu\u00eas de Oncologia de Lisboa Francisco Gentil"},{"name":"Faculdade de Medicina de Lisboa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2022,9,21]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21708"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2016.02.028"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.path.2015.07.007"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2003.11.005"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eucr.2021.101732"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/J.JURO.2007.03.024"},{"key":"e_1_3_2_8_2","first-page":"361","article-title":"Etude sur le seminome","author":"Masson P","year":"1946","unstructured":"Masson P.
