چکیده

INTRODUCTION Primary adenocarcinomas resembling submucosal tumors are rare in the gastrointestinal tract. Almost all the submucosal tumor-like adenocarcinomas previously reported invaded the submucosa or deeper. Therefore, submucosal tumor-like lesions are usually treated by surgical resection, and those that arise in the duodenum have been treated by pancreaticoduodenectomy. CASE PRESENTATION A 65-year-old Japanese man was diagnosed with a submucosal tumor-like adenocarcinoma in his duodenum. We considered it possible that the tumor invasion was limited to the mucosal or submucosal layers and could be removed by endoscopic resection. Tumor histopathology revealed a well-differentiated adenocarcinoma confined to the muscularis mucosae with no lymphovascular invasion. Complete resection of the carcinoma was achieved and there has been no recurrence three years after endoscopic resection. CONCLUSIONS We suggest that submucosal tumor-like adenocarcinomas arising in nonampullary duodenal sites should be diagnosed carefully with a view to possible endoscopic resection.

Repeatedly recurrent colon cancer involving the appendiceal orifice after endoscopic piecemeal mucosal resection: a case report.

Local recurrence after endoscopic piecemeal mucosal resection (EPMR) for colorectal tumors is a crucial issue. However, such recurrence is usually detected within one year and cured with additional endoscopic treatment, which makes EPMR acceptable. Herein, we report a rare case of repeatedly recurrent colon cancer involving the appendiceal orifice after EPMR, which was not cured with additional...

Case of a tumor comprising gastric cancer and duodenal neuroendocrine tumor

The present report describes a rare case of a tumor composed of early gastric cancer and a duodenal neuroendocrine tumor (NET). A 78-year-old woman underwent esophagogastroduodenoscopy at a local institution for screening of the upper gastrointestinal tract which revealed a protruded tumor through the pyloric ring from the pyloric antrum. The tumor was too large to treat at the facility; conseq...

tumors that account for 2 % to 13.6 % of all gastrointestinal carcinoids, and no guidelines are available for their treat− ment. Small (< 2 cm) nonperiampullary duodenal carcinoids without submucosal invasion have been termed early stage duodenal carcinoids (esDC) [1]; their clinical course appears favorable and en− doscopic treatment would seem to be a feasible treatment option. We report on a...

Feasibility of Endoscopic Resection for Sessile Nonampullary Duodenal Tumors: A Multicenter Retrospective Study

Objectives. Sessile nonampullary duodenal tumors (SNADTs) are relatively rare and endoscopic resection of these lesions is considered more challenging than in other parts of the gastrointestinal tract. The aim of this study was to evaluate the feasibility of endoscopic resection for SNADT. Methods. Medical records including endoscopic resection for SNADT from July 2002 to July 2013 from 5 cente...
