We herein report a case of neuroendocrine carcinoma of the gastric stump found 47 years after Billroth II gastric resection for a benign gastric ulcer. A 74-year-old man was referred to another hospital with melena. Endoscopic examination revealed a localized ulcerative lesion at the gastrojejunal anastomosis. The diagnosis by endoscopic biopsy was neuroendocrine carcinoma. A total gastrectomy ...

BACKGROUND Schwannomas, also known as neurilemmomas, are benign slow-growing neoplasms originating from a Schwann cell sheath. These neoplasms are rare among the mesenchymal tumors of the gastrointestinal tract. In the stomach, Schwannomas only represent 0.2 % of all gastric tumors; this makes the presentation of a schwannoma in the stomach of a man in his seventh decade unusual. This case repo...

A 73-year-old man was admitted to our hospital with complaints of tarry stools. He had been receiving warfarin anticoagulant therapy for severe left ventricular dysfunction. Prothrombin time international normalized ratio had been maintained within 2.0-3.0. Esophagogastroduodenalscopy revealed a polypoid lesion about 10 mm in diameter on the greater curvature of the stomach with oozing (Picture...

BACKGROUND AND STUDY AIMS A 49-year-old woman underwent an esophagogastroduodenoscopy as part of a health check at our hospital. Endoscopic observation revealed a flat elevated lesion 6 mm in diameter in the gastric antrum (Paris Classification type IIa). Magnifying endoscopy using narrow-band imaging showed a slightly irregular micro-surface pattern with round and oval pits, as well as a regul...

AIM To present a rarely diagnosed case of gastric Dieulafoy lesion. DESCRIPTION OF CASE A 62-year-old male was hospitalized with hematemesis. Laparoscopic ligature of two gastric ulcers located in the antrum was performed but the upper gastrointestinal bleeding was not stopped. The patient was transferred to another surgical clinic and he underwent an emergency abdominal laparotomy with re-su...

Breast cancer is the most common cancer in women. Metastatic disease involvement of the stomach is usually a manifestation of advanced disease. Isolated metastatic involvement of the stomach from a primary breast lesion is rare. These lesions can mimic primary gastric carcinoma and can be hard to distinguish due to very similar clinical, endoscopic and histological features. The authors here de...

was performed and demonstrated a large ulcerated lesion suggestive of malignancy in the gastric greater curvature (Fig. 1). Endoscopic biopsies revealed numerous filamentous clusters with sulfur granules suggestive of Actinomyces infection, without changes suggesting malignancy (Fig. 2). Abdominal computed tomography revealed an extensive gastric mass and various celiac lymphadenopathies (Fig. ...

We present herein the occurrence of multifocal adenocarcinomas with a minute signet ring cell carcinoma that arose within a gastric inverted hyperplastic polyp (IHP) in a 40-year-old woman. Endoscopic ultrasonography demonstrated a heterogeneous hypoechoic mass in the third layer of the gastric wall. The endoscopic submucosal dissection specimen measuring 3.5×3.2×1.8 cm was a well-circumscribed...

Pancreatic and gastric heterotopias are rare clinical entities which have been identified throughout the entire length of the gastrointestinal tract. Combined gastric and pancreatic heterotopias, although unusual, have been described in the duodenum and jejunum, and in other structures, including Meckel's diverticulum and the ampulla of Vater. We report a novel case of pancreatic and gastric he...

Inflammatory fibroid polyp (IFP) is a rare solitary gastrointestinal lesion of unknown etiology. It generally presents as polypoid mass in the gastric antrum. Mostly affects adults at average age of 60 years. IFP can cause different symptoms such as abdominal pain, gastrointestinal bleeding, intestinal obstruction or intussusception. IFP is a bening lesion and it may rarely mimic the submucosal...
