The patients had no history of previous surgical procedures or of malignancy elsewhere. The tumours in all three patients were located on the right lateral side of the neck; all patients underwent complete surgical resection of the mass. Grossly, the tumours were cystic and measured between 20 and 30\u2003mm in greatest diameter. Histologically, the tumours showed cyst walls lined by squamous epithelium. The cyst walls contained prominent germinal centres with lymphoid hyperplasia, cholesterol cleft granulomas, and scattered keratinized structures reminiscent of Hassall's corpuscles. In addition, a neoplastic cellular proliferation composed of round to oval cells arranged in sheets and originating from the lining of the cystic structures was present. The neoplastic cells showed moderate amounts of eosinophilic cytoplasm, round nuclei, and, in some areas, prominent nucleoli. Mitotic figures were easily found, and cellular pleomorphism was present in several areas. In two cases the tumours showed features of basaloid carcinoma of the thymus, while in one case the pattern was that of squamous cell carcinoma. Immunohistochemical studies for keratin showed a strong positive reaction in the tumour cells, while leucocyte common antigen strongly stained the lymphoid background. Follow\u2010up information obtained in two patients showed them to be alive 6\u2003months after initial diagnosis. One patient was lost to follow\u2010up.<\/jats:p><jats:p><jats:bold>Conclusion<\/jats:bold> :\u2002The cases described here represent an unusual variant of carcinoma arising in multilocular thymic cyst in the neck region.<\/jats:p>","DOI":"10.1111\/j.1365-2559.2004.01767.x","type":"journal-article","created":{"date-parts":[[2004,1,7]],"date-time":"2004-01-07T11:02:14Z","timestamp":1073473334000},"page":"64-68","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Carcinomas arising in multilocular thymic cysts of the neck: a clinicopathological study of three cases"],"prefix":"10.1111","volume":"44","author":[{"given":"C A","family":"Moran","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Suster","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"El\u2010Naggar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M A","family":"Luna","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,1,7]]},"reference":[{"key":"e_1_2_9_2_2","first-page":"71","volume-title":"Tumors of the upper aerodigestive tract and ear","author":"Mills SE","year":"1997"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198501000-00021"},{"key":"e_1_2_9_4_2","first-page":"301","article-title":"Cervical thymoma","volume":"60","author":"Bothra R.","year":"1975","journal-title":"Int.
