Herein is presented a case of FDCS of the small intestine with positivity for T\u2010cell antigen, simulating T\u2010cell lymphoma. An 82\u2010year\u2010old man consulted a doctor for a 1\u2003week history of epigastric pain. Imaging indicated a mass in the small intestine. Malignant lymphoma was suspected because of high serum levels of soluble interleukin\u20102 receptor, and resection of the tumor was performed. Microscopically the tumor consisted of large pleomorphic cells with reactive small lymphocytes. Most of the nuclei of the tumor cells were round or ovoid, and some of the tumor cells also had spindle\u2010shaped nuclei. Although the tumor cells were diffusely positive for CD45RO and CD4 on immunohistochemistry, negativity for pan\u2010T\u2010cell markers and CD56 was unusual for T\u2010cell lymphoma of intestinal origin. Additional immunohistochemistry demonstrated that the tumor cells were positive for follicular dendritic cell markers including CD23, CD35 and CAN.42, and diagnosis of FDCS was made. To the authors' knowledge this is the first case of FDCS aberrantly expressing CD45RO; FDCS expressing T\u2010cell markers can be a pitfall for diagnosis of FDCS.<\/jats:p>","DOI":"10.1111\/j.1440-1827.2009.02449.x","type":"journal-article","created":{"date-parts":[[2009,10,27]],"date-time":"2009-10-27T04:31:07Z","timestamp":1256617867000},"page":"809-812","source":"Crossref","is-referenced-by-count":14,"title":["Follicular dendritic cell sarcoma of small intestine with aberrant T\u2010cell marker expression"],"prefix":"10.1111","volume":"59","author":[{"given":"Yosuke","family":"Yamada","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hironori","family":"Haga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mako","family":"Hernandez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kanako C.","family":"Kubota","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumika","family":"Orii","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuo","family":"Nagashima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshihiro","family":"Matsuno","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,10,27]]},"reference":[{"key":"e_1_2_5_2_2","first-page":"90","article-title":"Extranodal follicular dendritic cell sarcoma of the gastrointestinal tract: Morphologic, immunohistochemical and ultrastructural analysis of two cases","volume":"103","author":"Hollowood K","year":"1995","journal-title":"Hematopathology"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1827.2008.02281.x"},{"key":"e_1_2_5_4_2","first-page":"363","volume-title":"WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues","author":"Chan JKC","year":"2008"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.2002.01418.x"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1309\/FY6PK436NBK0RYD4"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.1997.d01-553.x"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.prp.2008.03.009"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200302000-00017"},{"key":"e_1_2_5_10_2","doi-asserted-by":"crossref","first-page":"1693","DOI":"10.5858\/2000-124-1693-FDCSPA","article-title":"Follicular dendritic cell sarcoma presenting as a submucosal tumor of the stomach","volume":"124","author":"Han JH","year":"2000","journal-title":"Arch Pathol Lab Med"},{"key":"e_1_2_5_11_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.2001.01035.x"},{"key":"e_1_2_5_12_2","first-page":"223","article-title":"Metastatic follicular dendritic cell sarcoma of the stomach: A case report and review of the literature","volume":"67","author":"Geerts A","year":"2004","journal-title":"Acta Gastroenterol Belg"},{"key":"e_1_2_5_13_2","unstructured":"O'MallyD.Diagnosis: Follicular dendritic cell tumor mimicking GI stromal tumor.
