To determine the presence or absence of marginal zone B-cell lymphoma of MALT type and the splenic type among Waldeyer's ring (WR) lymphomas, 16 tonsillectomy specimens were studied. Ten cases (63%) were marginal zone B-cell lymphoma. Among marginal zone B-cell lymphoma, 7 were the MALT type and the remaining 3 cases of marginal zone B-cell lymphoma were the splenic type. Moreover, 4 cases of 7 MALT-type lymphomas contained numerous large cells (diffuse large B-cell lymphoma arising from a low-grade marginal zone B-cell lymphoma of MALT type). The low incidence of primary mucosa-associated lymphoid tissue type lymphoma of WR in previous reports may be because it is difficult to correctly identify the characteristic histologic findings of MALT-type lymphoma because of the small biopsy size.<\/jats:p>","DOI":"10.1177\/1066896907307039","type":"journal-article","created":{"date-parts":[[2008,4,16]],"date-time":"2008-04-16T12:20:29Z","timestamp":1208348429000},"page":"164-170","source":"Crossref","is-referenced-by-count":2,"title":["Marginal Zone B-Cell Lymphoma Among Primary B-Cell Lymphoma of Waldeyer's Ring: Histopathologic and Immunohistochemical Study of 16 Tonsillectomy Specimens"],"prefix":"10.1177","volume":"16","author":[{"given":"Masaru","family":"Kojima","sequence":"first","affiliation":[{"name":"Department of Pathology and Clinical Laboratories, Gunma Cancer Center Hospital,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoya","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Department of Radiology Gunma Cancer Center Hospital, Ohta"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiko","family":"Shimizu","sequence":"additional","affiliation":[{"name":"Department of Pathology, Tokai University School of Medicine, Isehara"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshio","family":"Tamaki","sequence":"additional","affiliation":[{"name":"Department of Pathology and Clinical Laboratories, Ashikaga Red Cross Hospital, Ashikaga"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideaki","family":"Itoh","sequence":"additional","affiliation":[{"name":"Department of Pathology and Clinical Laboratories, Maebashi Red Cross Hospital, Maebashi"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeo","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Department of Pathology and Clinical Laboratories, Nagoya University Hospital, Nagoya Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2008,4,1]]},"reference":[{"key":"atypb1","unstructured":"Isaacson PG, Norton AJ Extranodal Lymphomas.
