We report a LAMN surgical case whose appendiceal tumor penetrated the sigmoid colon wall. An 87\u2010year\u2010old man was referred for endoscopic resection (ER) of a colon polyp. Despite four ERs over 5\u2009years, the polyp recurred at the same site. Laparoscopic surgery revealed a dilated appendix firmly attached to the sigmoid colon. We performed en bloc resection of both the sigmoid colon and appendix without tumor exposure. The histopathological evaluation showed that the LAMN had penetrated the sigmoid colon wall, forming two polyps on the colonic mucosa. In cases where the appendiceal\u2010colonic fistula is suspected, en bloc resection of the appendix and colon wall should be considered.<\/jats:p>","DOI":"10.1111\/ases.13368","type":"journal-article","created":{"date-parts":[[2024,8,4]],"date-time":"2024-08-04T19:39:25Z","timestamp":1722800365000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Low\u2010grade
