Extranodal marginal zone lymphomas (EMZL) or mucosa-associated lymphoid tissue (MALT) lymphomas are the most common subtype. Almost half of all MALT lymphomas arise in the gastrointestinal (GI) tract and, while the stomach is the most common site of GI involvement, the small and large intestines can also be involved. Rare cases of MALT lymphoma involving the rectum have been reported; however, to our knowledge, involvement of the anal canal has never been reported in the literature. Here, we describe a unique case of MALT lymphoma of the anal canal. Infectious agents have been implicated in the pathogenesis of MALT lymphomas, possibly through persistent antigenic stimulation of the area; however, in our case no such infection was documented.","claims":[{"public_id":"cl_3dbd8e76099b2a475c971895a4a9a2ed","status":"active","text":"A unique case of mucosa-associated lymphoid tissue lymphoma involving the anal canal is described.","confidence":0.99,"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/claims/cl_3dbd8e76099b2a475c971895a4a9a2ed"},{"public_id":"cl_7dca3b062570b44e120a6d8190e6b32c","status":"active","text":"No infectious agent was documented in the reported case despite infectious agents being implicated in mucosa-associated lymphoid tissue lymphoma pathogenesis.","confidence":0.86,"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/claims/cl_7dca3b062570b44e120a6d8190e6b32c"}],"concepts":[{"public_id":"co_35afbbab7c1a7ac29730c7a483519878","status":"active","name":"mucosa-associated lymphoid tissue lymphoma","description":"An extranodal marginal zone lymphoma subtype arising from mucosal lymphoid tissue.","types":["disease","lymphoma subtype"],"aliases":["MALT lymphoma","extranodal marginal zone lymphoma"],"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/concepts/co_35afbbab7c1a7ac29730c7a483519878"},{"public_id":"co_6614f4e9dcd83f05fc4bbcee8636b865","status":"active","name":"anal canal","description":"The terminal segment of the gastrointestinal tract described as the site of the reported lymphoma.","types":["anatomical site"],"aliases":[],"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/concepts/co_6614f4e9dcd83f05fc4bbcee8636b865"},{"public_id":"co_c1b4355349d5b61e4a2b584269515e1f","status":"active","name":"infectious agents","description":"Microorganisms that may be associated with lymphoma pathogenesis through persistent antigenic stimulation.","types":["etiologic factor"],"aliases":[],"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/concepts/co_c1b4355349d5b61e4a2b584269515e1f"}],"external_ids":{"DOI":"10.1159/000495601","ArXiv":null,"PubMed":31207598,"PubMedCentral":null,"MAG":2949304085,"DBLP":null,"ACL":null},"open_access":{"is_open_access":false,"pdf_url":null,"landing_url":"https://sah.borca.ai/papers/190514479","source":null,"pdf_url_source":null,"license":null,"reason":"pdf_url_not_indexed"},"reference_availability":{"status":"available","references_indexed":true,"full_text_available":false,"full_text_source":null,"count_basis":"semantic_scholar_metadata","extraction_status":"not_applicable","reason":null},"source":{"provider":"episteme2","base_corpus":"semantic_scholar_dump","freshness_mode":"unknown","basis":["semantic_scholar_metadata","postgres_metadata"],"limits":["paper metadata is based on indexed upstream scholarly datasets","claims and concepts are available only for extracted papers","absence of claims or concepts means no extracted graph data is available in this response"],"status":"available","degraded":false,"degraded_reasons":[],"diagnostics":{"status":"available","degraded":false,"degraded_reasons":[],"metadata_status":"available","graph_status":"available","abstract_status":"available"},"source_flags":5},"paper_id":631759,"paper_uid":"7fa437eb-b5a3-49b4-817d-5509eb10c7ba","canonical_identity":{"paper_id":631759,"paper_uid":"7fa437eb-b5a3-49b4-817d-5509eb10c7ba","identity_status":"available","lookup_basis":"semantic_scholar_external_id","compatibility_path":"corpus_id"},"url":"https://sah.borca.ai/papers/190514479"}
