Infection, drug-induced enteritis, malignancy, vasculitis and Inflammatory bowel disease are the most common causes; their clinical expression often varies according to the site and severity of intestinal involvement. We report on a 68-year-old male presenting with dyspepsia and melena and multiple gastrointestinal ulcers on endoscopy. We could not establish diagnosis of peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) despite multiple biopsies taken on several endoscopic sessions, and cytomegalovirus (CMV) infection was documented by presence of inclusion bodies on pathology. The immunohistochemical study showed a mixture of B lymphocytes and predominantly T lymphocytes, negative for cluster of differentiation (CD)7.\u200aSouthern blot gene rearrangement was positive for T-cell receptor beta. Our patient eventually expired from a massive gastrointestinal hemorrhage following four cycles of chemotherapy. We wish to emphasize that a CMV infection, as a comorbidity, can potentially mask and delay diagnosis of PTCL-NOS, especially in cases with aberrant immunophenotype presentation. <\/jats:p>","DOI":"10.1055\/a-0869-7828","type":"journal-article","created":{"date-parts":[[2019,4,12]],"date-time":"2019-04-12T23:18:29Z","timestamp":1555111109000},"page":"E615-E620","source":"Crossref","is-referenced-by-count":1,"title":["Cytomegalovirus infection in a T-cell lymphoma patient presenting with multiple gastrointestinal ulcers: a case report"],"prefix":"10.1055","volume":"07","author":[{"given":"Jin","family":"Tao","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xian","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christ-Jonathan","family":"Tsia Hin Fong","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhuo","family":"Wen","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pathology, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiong","family":"Liang","sequence":"additional","affiliation":[{"name":"Department of Pathology, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qu","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Oncology, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2019,4,12]]},"container-title":["Endoscopy International Open"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/a-0869-7828.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T21:23:16Z","timestamp":1557177796000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/a-0869-7828"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,4]]},"references-count":0,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2019,3,15]]},"published-print":{"date-parts":[[2019,4]]}},"URL":"https:\/\/doi.org\/10.1055\/a-0869-7828","relation":{},"ISSN":["2364-3722","2196-9736"],"issn-type":[{"value":"2364-3722","type":"print"},{"value":"2196-9736","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,4]]}}}
