A 58\u2010year\u2010old woman suspected of gallbladder carcinoma underwent laparoscopic cholecystectomy. Microscopic examination of the gallbladder demonstrated lymphoid cell infiltration forming lymphoid follicles with hyperplastic secondary follicles. The surrounding monocytoid B cells and centrocyte\u2010like cells selectively infiltrated the crypt epithelium forming lympho\u2010epithelial lesions. Plasma cells were also noted beneath the mucosal epithelium. Bile culture revealed the Gram\u2010negative bacilli <jats:italic>Enterococcus faecalis<\/jats:italic> and <jats:italic>Morganella\n morganii<\/jats:italic>. Immunoglobulin heavy chain gene rearrangement was confirmed using polymerase chain reaction (PCR) and oligoclonal lymphoid proliferations was detected. Because autoimmune diseases, or chronic inflammatory disorders, seem to correlate with the occurrence of MALT lymphoma, Gram\u2010negative bacterial infection could also be considered as a prodrome of MALT lymphoma of the gallbladder.<\/jats:p>","DOI":"10.1046\/j.1440-1827.2001.01299.x","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T17:16:07Z","timestamp":1047489367000},"page":"965-969","source":"Crossref","is-referenced-by-count":23,"title":["Primary low\u2010grade MALT lymphoma of the gallbladder"],"prefix":"10.1111","volume":"51","author":[{"given":"Tomoshi","family":"Tsuchiya","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isao","family":"Shimokawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshikazu","family":"Higami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Ohtani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuji","family":"Shigeoka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koichi","family":"Ohshima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Tanaka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyoshi","family":"Ayabe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2002,2,13]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19831015)52:8<1410::AID-CNCR2820520813>3.0.CO;2-3"},{"key":"e_1_2_6_3_2","first-page":"14","article-title":"Extranodal lymphomas: the MALT concept.","volume":"76","author":"Isaacson PG.","year":"1992","journal-title":"Verh.
