A small colon tumour was found in a 56-year-old man during diagnostic colonoscopy performed after a positive faecal occult blood test, and he was referred for treatment. A slightly reddish superficial elevated lesion with a shallow depression 10\u2005mm in size was found in the transverse colon. Magnifying narrow-band imaging revealed disrupted irregular microvessels and the absence of a surface pattern in the depressed area. En bloc endoscopic mucosal resection (EMR) of the tumour was undertaken. The tumour was positive for chromogranin A and synaptophysin, and had a mitotic rate of &gt;20\/10 high-power fields and a Ki-67 proliferative index of &gt;50%; it was diagnosed as a neuroendocrine carcinoma. The tumour minimally invaded the submucosa (300\u2005\u03bcm) without lymphovascular involvement. The patient was followed up carefully, and at 1\u2005year after EMR, no recurrence was found using colonoscopy and CT scans.<\/jats:p>","DOI":"10.1136\/bcr-2014-208148","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T05:56:44Z","timestamp":1425362204000},"page":"bcr2014208148","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Endoscopic mucosal resection of early stage colon neuroendocrine carcinoma"],"prefix":"10.1136","volume":"2015","author":[{"given":"Yasushi","family":"Yamasaki","sequence":"first","affiliation":[{"name":"Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriya","family":"Uedo","sequence":"additional","affiliation":[{"name":"Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryu","family":"Ishihara","sequence":"additional","affiliation":[{"name":"Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuhiko","family":"Tomita","sequence":"additional","affiliation":[{"name":"Department of Pathology, Osaka Medical Center for Cancer and Cardiovascular Diseases, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,3,3]]},"reference":[{"key":"2025082803303128000_2015.mar03_1.bcr2014208148.1","doi-asserted-by":"publisher","DOI":"10.1245\/s10434-014-3725-3"},{"key":"2025082803303128000_2015.mar03_1.bcr2014208148.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.surg.2013.11.012"},{"key":"2025082803303128000_2015.mar03_1.bcr2014208148.3","doi-asserted-by":"publisher","DOI":"10.1007\/s10350-003-0038-1"},{"key":"2025082803303128000_2015.mar03_1.bcr2014208148.4","unstructured":"Bosman FT , Carneiro F , Hruban RH , et al .
