A 33-year-old male presented with a 10-day history of non-productive cough and fever. Investigation revealed mediastinal widening without pulmonary involvement. Computed tomography showed a large mass-14.8 \u00d7 10.8 \u00d7 8.4 cm-in the mid-posterior mediastinum, and a biopsy obtained by video-assisted thoracoscopy indicated that the mass was a tumor. Immunohistochemistry showed combined thymoma type AB1. Because of the considerable proportions of the tumor and its close proximity to major structures, the patient was treated with chemotherapy.<\/jats:p>","DOI":"10.1590\/0100-3984.2014.0025","type":"journal-article","created":{"date-parts":[[2017,1,14]],"date-time":"2017-01-14T21:45:02Z","timestamp":1484430302000},"page":"403-405","source":"Crossref","is-referenced-by-count":2,"title":["Massive thymoma of the mid-posterior mediastinum: an unprecedented case in a young adult"],"prefix":"10.1590","volume":"49","author":[{"given":"Karen Fernandes de","family":"Oliveira","sequence":"first","affiliation":[{"name":"Hospital Universit\u00e1rio de Bras\u00edlia,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcio Maciel","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Instituto do C\u00e2ncer do Estado de S\u00e3o Paulo Octavio Frias de Oliveira,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gesner Pereira","family":"Lopes","sequence":"additional","affiliation":[{"name":"Universidade Federal do Tri\u00e2ngulo Mineiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renan Sandoval de","family":"Almeida","sequence":"additional","affiliation":[{"name":"Universidade Federal de Uberl\u00e2ndia,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juliana Lopes","family":"Lusvarghi","sequence":"additional","affiliation":[{"name":"Hospital Heli\u00f3polis,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo\u00e3o Paulo Vieira dos","family":"Santos","sequence":"additional","affiliation":[{"name":"Universidade Federal do Tri\u00e2ngulo Mineiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"issue":"664-7","key":"ref1","article-title":"A case of middle mediastinal thymoma","volume":"60","author":"Shikada Y","year":"2012","journal-title":"Gen Thorac Cardiovasc Surg"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1007\/s13244-012-0201-0","article-title":"A diagnostic approach to the mediastinal masses","volume":"4","author":"Juanpere S","year":"2013","journal-title":"Insights Imaging"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"611","DOI":"10.1136\/pgmj.60.707.611","article-title":"Thymoma presenting as a middle mediastinal mass","volume":"60","author":"Bradford R","year":"1984","journal-title":"Postgrad Med J"},{"key":"ref4","first-page":"777","article-title":"Thymoma of the middle mediastinum: case report","volume":"26","author":"Wu Z","year":"2010","journal-title":"Chinese J Med Imaging Technol"},{"key":"ref5","first-page":"508","article-title":"A rare case of middle mediastinal thymoma mimicking left lower lobe lung tumor","volume":"60","author":"Venayaga K","year":"2005","journal-title":"Med J Malaysia"},{"key":"ref6","first-page":"343","article-title":"Middle mediastinal thymoma simulating pericardial cyst","volume":"62","author":"Adebonojo SA","year":"1977","journal-title":"Int Sur"},{"key":"ref7","doi-asserted-by":"crossref","DOI":"10.1016\/j.athoracsur.2012.08.065","article-title":"Video-assisted thoracoscopic surgery for ectopic mediastinal thymoma in a patient with myasthenia gravis","volume":"95","author":"Koezuka S","year":"2013","journal-title":"Ann Thorac Surg"},{"key":"ref8","doi-asserted-by":"crossref","first-page":"267","DOI":"10.5090\/kjtcs.2012.45.4.267","article-title":"Thymoma of the middle mediastinum","volume":"45","author":"Chung SR","year":"2012","journal-title":"Korean J Thorac Cardiovasc Surg"},{"key":"ref9","doi-asserted-by":"crossref","first-page":"486","DOI":"10.1177\/0218492312440264","article-title":"Myasthenia gravis complicated with lung cancer and middle mediastinal thymoma","volume":"20","author":"Takizawa M","year":"2012","journal-title":"Asian Cardiovasc Thorac Ann"},{"key":"ref10","first-page":"35","article-title":"Cystic thymoma in middle mediastinum -
