INTRODUCTION: When gastric cancer or carcinoid patients have coexisting diseases such as duodenal adenoma, FAP, or Crohn's disease, periodic observation of the duodenum is necessary. METHODS: Between August 2013 and April 2015, we performed four consecutive laparoscopic total gastrectomies with double tract reconstruction for duodenal surveillance. Three of the patients were diagnosed with gastric cancer, while the remaining patient was diagnosed with gastric carcinoid...

INTRODUCTION: Gastric carcinoid is a rare entity with complex management options. This study aims to determine if surgical intervention in patients with local, regional, and metastatic gastric carcinoid is associated with prolonged survival. MATERIALS AND METHODS: The California Cancer Registry merged with the California Office of Statewide Health Planning and Development was queried for patients with a diagnosis of gastric carcinoid (2000 to 2011). Clinicopathologic characteristics, management, and outcomes were evaluated...

Glomus tumour (GT) is a rare mesenchymal tumour of the stomach with Gastrointestinal Stromal Tumour (GIST), leiomyoma and schwannoma being far more common and comprising more than 90% of all gastric mesenchymal tumours. As glomus bodies are located in the peripheral parts of the human body, these tumours are peripherally located, classically the subungual region, hands, feet and trunk. While being evaluated for renal problems, a middle aged lady was incidentally found to have a gastric tumour. This was submucosal in location and was excised by a wedge resection and reported elsewhere as carcinoid tumour...

Solid-pseudopapillary neoplasm (SPN) of the pancreas is a rare tumor that accounts for less than one percent of pancreatic tumors. The diagnosis could be challenging as SPN tend to manifest with nonspecific abdominal symptoms, variable radiological features, and inconsistent morphology. The cellular origin of SPN is unclear and might involve ductal, acinar and endocrine stem cells.  We report a rare case of a 27-year-old female who presented with intermittent abdominal pain for two years, associated with a decrease in appetite...

The incidence of gastric and rectal carcinoids is increasing. This is probably due to endoscopic screening. The prognosis is primarily dependent upon tumor size, aggressiveness (pathology, Ki-67), metastatic disease and stage. However, neuroendocrine carcinoma usually behaves as an adenocarcinoma.

PURPOSE OF REVIEW: Neuroendocrine tumors (NETs) were initially identified as a separate entity in the early 1900s as a unique malignancy that secretes bioactive amines. GI-NETs are the most frequent type and represent a unique subset of NETs, because at least 75% of these tumors represent gastrin stimulation of the enterochromaffin-like cell located in the body of the stomach. The purpose of this review is to understand the specific role of gastrin in the generation of Gastric NETs (G-NETs)...

Although gastric tumors have overlapping radiologic appearances, some unusual tumors may present specific imaging features. Using multidetector computed tomography (MDCT), with water as a negative oral contrast agent and intravenous contrast medium, can provide critical information for the diagnosis of gastric diseases. In addition, MDCT can evaluate the involvement of the gastric wall and extragastric extent of the disease, as compared with gastroenteroscopy and double-contrast upper gastrointestinal study...

BACKGROUND: Autoimmune gastritis (AIG) and adenocarcinoma-associated chronic atrophic gastritis (CAG) are both associated with oxyntic atrophy, but AIG patients demonstrate an increased risk of carcinoid tumors rather than the elevated risk of adenocarcinoma observed with CAG. We therefore sought to compare the characteristics of the metaplastic mucosa in AIG and CAG patients. METHODS: We examined markers for metaplasia (spasmolytic polypeptide expressing metaplasia (SPEM) and intestinal metaplasia) as well as proliferation (Ki67) and immune cell populations (neutrophils, macrophages, and eosinophils) in gastric sections from 16 female patients with autoimmune thyroiditis and AIG and 17 patients with CAG associated with gastric adenocarcinoma...

Background: Gastrin, which induces gastric acid secretion, and a structurally similar hormone, cholecystokinin (CCK)-a potent acid inhibitor, may each play a role in gastric cancer. However, few studies have investigated this hypothesis in humans. We therefore investigated whether serum gastrin or CCK concentrations at baseline were associated with the incidence of gastric non-cardia adenocarcinomas (GNCA), oesophagogastric junctional adenocarcinomas (EGJA) or gastric carcinoid tumours over 24 years of follow-up in a study nested within the all-male Alpha-Tocopherol, Beta-Carotene Cancer Prevention (ATBC) Study of Finnish smokers...

Gastric carcinoid tumor is rarely diagnosed in children. We report a case of gastric carcinoid tumor that occurred after allogeneic HSCT. A 13-year-old girl with ETP acute lymphoblastic leukemia underwent allogeneic HSCT from a 7/8 HLA-matched unrelated donor. She presented with rashes, abdominal pain, and diarrhea, which were suggestive of GVHD, 7 months after HSCT. Immunosuppressive agents failed to resolve these symptoms well. After a series of evaluations, carcinoid syndrome caused by a gastric carcinoid tumor was diagnosed...

An 80 year-old female presented with ductal breast carcinoma (stage II) three years ago, complained of asthenia and iron-deficiency anemia. No diagnosis was obtained after conventional endoscopy and iron supplements were indicated. Ten months later visible digestive hemorrhage was presented. Upper and lower endoscopy was repeated but non-diagnosis was obtained. Thus, video capsule endoscopy was indicated identifying a stenotic lesion arising in the mucosa of distal jejunum. Histopathological examination revealed a poorly mucinous differentiated signet-ring cell adenocarcinoma with an intense peri-tumoral lymphoid (Crohn´s-like lymphoid reaction) and lympho-vascular infiltration with no nodal metastases (pT3N0;7ª edition TNM classification)...

BACKGROUND: While neuroendocrine (carcinoid) tumors are increasingly recognized in the adult population, they are often not suspected in children. PROCEDURE: Retrospective review of all well-differentiated neuroendocrine (carcinoid) tumors was performed based on pathology reports from a quaternary pediatric medical center between January 2003 and June 2016. Clinical presentations, treatment approaches, imaging findings, and outcomes were reviewed and analyzed. RESULTS: A total of 45 cases of pathology-proven carcinoid tumor were reported with an average age of 14...

We report a unique case of synchronous double primary gastric cancer consisting of adenocarcinoma components with micropapillary features and composite glandular-endocrine cell carcinoma components. The patient was a 53-year-old man presenting with a 6-month history of epigastric pain and diarrhea. A subtotal gastrectomy was performed. Histologically, one tumor was composed of micropapillary carcinoma components (50%) with tight clusters of micropapillary aggregates lying in the empty spaces, admixed with moderately differentiated adenocarcinoma components...

BACKGROUND: Atrophic gastritis (AG) is at increased risk of gastric neoplasia, thus surveillance gastroscopy has been proposed. AIMS: To assess cost of detecting gastric neoplasias by surveillance endoscopy according to identified risk factors in Italy. METHODS: Post-hoc analysis of a cohort study including 200 AG-patients from Italy followed up for a mean of 7.5 (4-23.4) years was done. Considered risk factors were: age >50years, extensive atrophy, pernicious anaemia, OLGA-OLGIM scores 3-4 at diagnosis...

Background and study aims: Gastric neuroendocrine tumors (NETs) are rare lesions that develop from neuroendocrine cells. NETs are classified into 3 types based on the rate of mitosis and Ki-67 labeling index; the NET G1 type is synonymously referred to as carcinoid. Gastric NETs are usually discovered as submucosal tumors during upper gastrointestinal endoscopic examination. This study reports a rare case of pedunculated gastric NET. The lesion was found as a result of gastroendoscopy. The gastric lesion was a pedunculated polyp with a reddish head...

BACKGROUND/AIMS: Chromogranin A is an important tool in the diagnosis of neuroendocrine tumors. Autoimmune gastritis is an autoimmune disorder marked by hypergastrinemia, which stimulates enterochromaffin-like cell proliferation. Chromogranin A is also elevated in autoimmune gastritis patients with a different level of increase in each patient. The goal of this study is to explore constituents that influence serum chromogranin A levels in autoimmune gastritis patients. MATERIALS AND METHODS: One hundred and eighty-eight autoimmune gastritis patients and 20 patients with type I gastric carcinoid tumors were analyzed retrospectively and compared to 110 functional dyspepsia patients in terms of factors that might affect serum chromogranin A levels...

We report the case of a 42 year male with history of chronic anaemia who was found to have pernicious anaemia with beta thalassemia trait and had on esophago-gastric-duodenoscopy, gastric carcinoids with gastric atrophy. Pernicious anaemia and gastric carcinoids occurring simultaneously in a single individual is rare. Our case emphasises the need for esophago-gastric-duodenoscopy in cases of pernicious anaemia.

Literature on non-ampullary-duodenal carcinomas is limited. We analyzed 47 resected non-ampullary-duodenal carcinomas. Histologically, 78% were tubular-type adenocarcinomas mostly gastro-pancreatobiliary type and only 19% pure intestinal. Immunohistochemistry (n=38) revealed commonness of 'gastro-pancreatobiliary markers' (CK7 55, MUC1 50, MUC5AC 50, and MUC6 34%), whereas 'intestinal markers' were relatively less common (MUC2 36, CK20 42, and CDX2 44%). Squamous and mucinous differentiation were rare (in five each); previously, unrecognized adenocarcinoma patterns were noted (three microcystic/vacuolated, two cribriform, one of comedo-like, oncocytic papillary, and goblet-cell-carcinoid-like)...
