ITCL, not otherwise specified (ITCL, NOS) which is a type of ITCL is particularly rare. There are few case reports of ITCL, NOS but no previous reports describe its endoscopic features. In this report, the 69\u2010year\u2010old man was diagnosed with ITCL, NOS. Colonoscopy revealed the elevated legion and edematous mucosa with focal depressions in the lower rectum. On the depressed legions, magnifying endoscopy combined with narrow\u2010band imaging detected the disappearance of glandular structure and branching abnormal blood vessels like a tree. These findings were similar to the tree\u2010like appearance,\u00a0which has been described as a unique feature of gastric mucosal\u2010associated lymphoid tissue lymphoma. The targeted biopsy of the tree\u2010like appearance showed abnormal histopathological findings which fit the definition of ITCL, NOS. He was treated with chemotherapy and achieved complete remission. As is the case of gastric mucosal\u2010associated lymphoid tissue lymphoma, the tree\u2010like appearance\u00a0is possibly the unique sign of ITCL, NOS. We report the endoscopic features of ITCL, NOS and show characteristic findings by magnifying endoscopy\u00a0combined with narrow\u2010band imaging.<\/jats:p>","DOI":"10.1002\/deo2.319","type":"journal-article","created":{"date-parts":[[2023,11,27]],"date-time":"2023-11-27T19:55:51Z","timestamp":1701114951000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A
