Diagnostic imaging showed anterior mediastinal masses, and surgical resection was accomplished in all cases. Grossly, the tumours measured 40\u201390\u00a0mm in greatest diameter (average: 65\u00a0mm), and were described as ill\u2010defined lesions with a prominent cystic component and focal areas of haemorrhage and necrosis. Histologically, they were characterized predominantly by their cystic architecture. The cyst walls were lined by squamous epithelium showing different degrees of cellular atypia. In focal, more solid areas, the tumours showed evidence of keratinization. By immunohistochemistry, tumour cells were positive for cytokeratin 5\/6, p40, and Pax8. All tumours were staged as T1N0M0 according to the Weissferdt\u2013Moran staging system. Clinical follow\u2010up showed that four patients have remained alive and well after a period ranging from 1 to 2\u00a0years. Two patients were lost to follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The current cases highlight an uncommon growth pattern of well\u2010differentiated squamous cell carcinoma of the thymus that may cause diagnostic difficulty with mediastinoscopic biopsies.<\/jats:p><\/jats:sec>","DOI":"10.1111\/his.12748","type":"journal-article","created":{"date-parts":[[2015,6,1]],"date-time":"2015-06-01T22:10:21Z","timestamp":1433196621000},"page":"333-338","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Cystic well\u2010differentiated squamous cell carcinoma of the thymus: a clinicopathological and immunohistochemical study of six cases"],"prefix":"10.1111","volume":"68","author":[{"given":"Annikka","family":"Weissferdt","sequence":"first","affiliation":[{"name":"Department of Pathology The University of Texas MD Anderson Cancer Center Houston TX USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neda","family":"Kalhor","sequence":"additional","affiliation":[{"name":"Department of Pathology The University of Texas MD Anderson Cancer Center Houston TX USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cesar A","family":"Moran","sequence":"additional","affiliation":[{"name":"Department of Pathology The University of Texas MD Anderson Cancer Center Houston TX USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,7,14]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-198207000-00007"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-198210000-00003"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199002000-00007"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199001000-00003"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19910215)67:4<1025::AID-CNCR2820670427>3.0.CO;2-F"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1309\/AJCP88FZTWANLRCB"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199807000-00009"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199906000-00009"},{"key":"e_1_2_7_10_1","first-page":"433","article-title":"Histochemical and immunohistochemical evidence of glandular differentiation in thymic carcinoma","volume":"39","author":"Matsuno Y","year":"1989","journal-title":"Acta Pathol.
