title: Lymphomas of the Gastrointestinal Tract: An Update.
abstract: The gastrointestinal tract is the most common extranodal site of non-Hodgkin lymphoma. Certain lymphomas have a predilection for the gastrointestinal tract, including extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue, mantle cell lymphoma, natural killer/T-cell lymphoma, and enteropathy-associated T-cell lymphoma. Follicular lymphoma may also be primary to the gastrointestinal tract. In addition to diagnosing neoplastic conditions, it is important to differentiate lymphomas from atypical reactive proliferations. Recent research relevant to non-Hodgkin lymphomas involving this location is reviewed with an emphasis on novel and evolving areas of classification.
