In both cases, type A (infundibular\u2010like keratinized) epithelia were observed. In type A epithelia, CK 1 and 10 expressions were decreased, and CK 14 and 17 were detectable in the whole layers. CK 7, 8, 15, 16 and 18 were not detected in type A epithelia. In tumor nests of well\u2010differentiated SCC, CK 1 and 10 expressions were downregulated, and CK 14 expression was upregulated. In tumor nests of poorly differentiated SCC, CK 1 and 10 were not expressed, but simple epithelial keratins (CK 8, 18 and 19) were expressed. These changes of CK expression are related to malignant transformation from the sinus tract (type A epithelium) in HS to SCC.<\/jats:p>","DOI":"10.1111\/j.1600-0560.2006.00680.x","type":"journal-article","created":{"date-parts":[[2006,12,15]],"date-time":"2006-12-15T00:58:41Z","timestamp":1166144321000},"page":"675-678","source":"Crossref","is-referenced-by-count":19,"title":["Cytokeratin expression in squamous cell carcinoma arising from hidradenitis suppurativa (acne inversa)"],"prefix":"10.1111","volume":"34","author":[{"given":"Ichiro","family":"Kurokawa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keisuke","family":"Nishimura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kei\u2010ichi","family":"Yamanaka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hitoshi","family":"Mizutani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Airo","family":"Tsubura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean","family":"Revuz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,8,10]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/120347540300700109"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1468-3083.2001.00303.x"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(82)90400-7"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2133.1999.02970.x"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/147323000203000205"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1083\/jcb.95.2.414"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749-6632.1985.tb50415.x"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2133.1993.tb03511.x"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0560.1999.tb01814.x"},{"key":"e_1_2_5_11_2","first-page":"89","article-title":"Suprabasal 40 kd keratin (K19) expression as an immunohistologic marker of pregnancy in oral epithelium","volume":"134","author":"Lindberg K","year":"1989","journal-title":"Am J Pathol"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000441-200503000-00008"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/1523-1747.ep12486607"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2133.1996.d01-901.x"},{"key":"e_1_2_5_15_2","doi-asserted-by":"publisher","DOI":"10.1097\/00054725-200111000-00008"},{"key":"e_1_2_5_16_2","doi-asserted-by":"publisher","DOI":"10.1067\/mjd.2003.10"}],"container-title":["Journal of Cutaneous Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1600-0560.2006.00680.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1600-0560.2006.00680.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,10]],"date-time":"2023-10-10T19:41:47Z","timestamp":1696966907000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1600-0560.2006.00680.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,8,10]]},"references-count":15,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2007,9]]}},"alternative-id":["10.1111\/j.1600-0560.2006.00680.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1600-0560.2006.00680.x","archive":["Portico"],"relation":{},"ISSN":["0303-6987","1600-0560"],"issn-type":[{"value":"0303-6987","type":"print"},{"value":"1600-0560","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,8,10]]}}}
