It has an immunophenotype similar to that of other FLs and usually carries the typical t(14;18)(q32;q21) translocation. However, unlike other FLs, D-FL is almost always diagnosed at a low stage and stays localized to the small intestine, most commonly the second portion of the duodenum, whereas the vast majority of other FLs are diagnosed at an advanced stage. Additionally, D-FL gene expression and pathogenesis appear to be more closely related to extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue than to other types of FL. Therefore, many oncologists have opted to treat this variant of FL in a \u201cwatch and wait\u201d manner because of its excellent prognosis and the rarity of D-FL to progress even when no treatments are attempted.<\/jats:p>","DOI":"10.5858\/arpa.2016-0519-rs","type":"journal-article","created":{"date-parts":[[2018,3,22]],"date-time":"2018-03-22T10:16:58Z","timestamp":1521713818000},"page":"542-547","source":"Crossref","is-referenced-by-count":46,"title":["Duodenal-Type Follicular Lymphoma: A Clinicopathologic Review"],"prefix":"10.5858","volume":"142","author":[{"given":"Etan","family":"Marks","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Shi","sequence":"additional","affiliation":[{"name":"From the Department of Pathology, Montefiore Medical Center\/Albert Einstein College of Medicine, Bronx, New York."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3906","reference":[{"issue":"8","key":"2020081300224523600_i1543-2165-142-4-542-b01","doi-asserted-by":"crossref","first-page":"2780","DOI":"10.1200\/JCO.1998.16.8.2780","article-title":"New approach to classifying non-Hodgkin's lymphomas: clinical features of the major histologic subtypes: Non-Hodgkin's Lymphoma Classification Project","volume":"16","author":"Armitage","year":"1998","journal-title":"J Clin Oncol"},{"key":"2020081300224523600_i1543-2165-142-4-542-b02","unstructured":"Swerdlow \n              SH.\n            \n            \n              Campo \n              E.\n            \n            \n              Harris \n              NL.\n            \n            et al. \n          WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues.
