We report a rare case of heterotopic gastric mucosa presenting in a jejunal polyp of a 9-year-old girl, diagnosed with capsule endoscopy and laparoscopic exploration, after a 15-month history of lower gastrointestinal bleeding and anaemia. During surgery, the jejunal segment containing the polyp was resected and pathological examination revealed a polyp with gastric heterotopia. Heterotopic gastric mucosa is a rare pathology characterised by the presence of gastric mucosa outside of the stomach. Heterotopic gastric mucosa usually occurs in the oesophagus, duodenum, Meckel's diverticulum and enteric duplication cysts...

Fibrovascular polyps are rare, pedunculated, tumor-like lesions that are usually found in the esophagus; occurrence in the stomach is very rare. To our knowledge, sonographic and CT findings of a fibrovascular polyp in the stomach have never been reported. Here, we report a case of a fibrovascular polyp that was identified in the gastric antrum and prolapsed into the duodenal bulb. Sonography revealed a hyperechoic polypoid mass in the gastric antrum, which prolapsed into the duodenal bulb upon a change in the patient's position...

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...

Gastric fundic gland polyps (FGPs) are common non-adenomatous gastric polyps arising from normal fundic mucosa without Helicobacter pylori (H. pylori) infection. Although systemic FGPs associated with familial adenomatous polyposis (FAP) often have dysplasia, there are few reports of dysplasia occurring in sporadic FGPs, especially when detected by magnifying endoscopy with narrow band imaging (ME-NBI). We experienced two cases of adenocarcinoma occurring in sporadic FGPs, and their ME-NBI findings were very useful for differentiating FGP with cancer from non-dysplastic FGP...

REVIEW
Adam Roman Markowski, Agnieszka Markowska, Katarzyna Guzinska-Ustymowicz
Gastric polyps become a major clinical problem because of high prevalence and tendency to malignant transformation of some of them. The development of gastric hyperplastic polyps results from excessive proliferation of foveolar cells accompanied by their increased exfoliation, and they are macroscopically indistinguishable from other polyps with lower or higher malignant potential. Panendoscopy allows detection and differentiation of gastric polyps, usually after obtaining histopathological biopsy specimens...

In this article we present the case and images of an infrequent submucosal gastric tumor: an inflammatory fibroid polyp or Vanek´s tumor. When the tumor size exceeds the centimeter, it may be difficult to differentiate from malignant lesions. Endoscopic removal may be feasible and curative.

BACKGROUND: In a large number of patients with multiple gastrointestinal adenomatous polyps, no causal germline mutation can be found. Non-genetic factors may contribute to the development of adenomatous polyps in these unexplained polyposis patients. In the development of gastrointestinal cancer, prior exposure to abdominal radiotherapy has been identified as such a factor, as it increases the gastrointestinal cancer risk in cancer survivors. A relationship of radiotherapy with intestinal polyposis, however, has not yet been described...

The modalities to treat bleeding polyps include electrocautery snare polypectomy, adrenaline injection, clipping, argon plasma coagulation and surgery. We hereby describe an endoscopic banding ligation method for the management of bleeding gastric polyp in a patient receiving antiplatelet therapy. A 66-year-old man presented with a five month-history of intermittent tarry stool passage, nausea and fatigue. He had a past history of peripheral arterial occlusive disease and non-insulin dependent diabetes mellitus with end stage renal disease, and regularly took antiplatelet agent (ticlopidine 100 mg thrice daily) for cardiovascular prophylaxis...

Comparative efforts to understand the body plan evolution of stalked jellyfishes are scarce. Most characters, and particularly internal anatomy, have neither been explored for the class Staurozoa, nor broadly applied in its taxonomy and classification. Recently, a molecular phylogenetic hypothesis was derived for Staurozoa, allowing for the first broad histological comparative study of staurozoan taxa. This study uses comparative histology to describe the body plans of nine staurozoan species, inferring functional and evolutionary aspects of internal morphology based on the current phylogeny of Staurozoa...

Objective We have recently discovered new gastric lesions with black spots. There have been no reports about black spots and their clinicopathological features. We therefore report the clinicopathological features of black spots and assess their causes and mechanisms. Methods Sixty-four patients with black spots among 26,620 Japanese patients that underwent endoscopy between May 2012 and October 2014 were enrolled. Endoscopic findings of black spots were defined as black pigmentations in the gastric mucosa by conventional endoscopy...

Background/Aims: Several studies suggest that pyogenic liver abscess (PLA) is associated with colon neoplasm. A colonoscopic exam for cryptogenic PLA might detect a hidden colon neoplasm, through which intestinal flora can be transmitted into the liver. However, there are no prospectively enrolled cross-sectional data for colonic neoplasm in cryptogenic PLA. Methods: Patients with PLA were prospectively enrolled from two university hospitals. Among them, all the patients with cryptogenic PLA were recommended for colonoscopic exam to check for colonic neoplasm...

BACKGROUND: Gastric pyloric gland adenomas (PGAs) are rare epithelial polyps that are more commonly found in autoimmune atrophic gastritis and familial adenomatous polyposis. Little is known about the morphology and genetics of PGAs in familial adenomatous polyposis. AIMS: PGAs in familial adenomatous polyposis are studied morphologically and genetically. Findings in FAP associated PGAs are compared to sporadic PGAs and related lesions such as oxyntic gland adenoma (OGA) to increase our understanding of these rare polyps...

BACKGROUND: Numerous etiologies are implicated in the complications of diabetes. A link between diabetes and the predisposition to certain cancers, including colon cancer, has been established during the last decade. However, the relationship between fecal occult blood test (FOBT), a screening method used principally for detection of colon cancer, and diabetes has not been explored. METHODS: We investigated the association of positive FOBT with HbA1c of 5.70-6.49% (prediabetes) and HbA1c of ≥6...

BACKGROUND: Gastric foveolar hyperplastic polyps (GFHPs) are common findings in clinical practice. GFHPs commonly arise in a background of chronic atrophic gastritis, including autoimmune gastritis (type A gastritis), and have a potential risk of malignant transformation. CASE PRESENTATION: In 2005, a 55-year-old Japanese woman underwent upper endoscopy at another hospital and was found to have a pedunculated polyp (10 mm in diameter) on the greater curvature of the lower gastric body...

Wegener's granulomatosis is an uncommon inflammatory disease that manifests as vasculitis, granulomatosis, and necrosis. It usually involves the upper and lower respiratory tracts and kidneys. Although it may essentially involve any organ, gastrointestinal (GI) involvement is notably uncommon. A 20-year-old male patient presented with epigastric pain, vomiting, hematemesis, and melena. On physical examination, he was pale. There was no abdominal tenderness or organomegaly. Upper GI endoscopy revealed dark blue-colored infiltrative lesions in prepyloric area...

Gastrointestinal xanthomas are infrequent non-neoplastic lesions characterized by the accumulation of foam cells in the lamina propria. They are commonly seen in association with dyslipidemia, chemotherapy or radiotherapy, and infections in immunosuppressed patients. However, no clear connection to hyperlipidemia has been found. They occur more frequently in the stomach, and are very rare in the small bowel and esophagus. We identified all cases of non-gastric xanthoma or xanthomatosis reported in the English literature by searching the PubMed database and retrospectively reviewed the clinical, endoscopic, and histopathologic features of the 11 cases of non-gastric gastrointestinal xanthomas diagnosed in our hospital...

Bmps are morphogens involved in various gastric cellular functions. Studies in genetically-modified mice have shown that Bmp disruption in gastric epithelial and stromal cell compartments leads to the development of tumorigenesis. Our studies have demonstrated that abrogation of gastric epithelial Bmp signaling alone was not sufficient to recapitulate the neoplastic features associated with total gastric loss of Bmp signaling. Thus, epithelial Bmp signaling does not appear to be a key player in gastric tumorigenesis initiation...

Gastric polyps occur in 1-4 % of patients undergoing gastroscopy. Although most are sporadic, some gastric polyps are part of an underlying hereditary syndrome. Gastric polyps can be seen in each of the well-known gastrointestinal polyposis syndromes, but also in Lynch syndrome and in several rare not primarily gastrointestinal syndromes. In addition, Gastric Adenocarcinoma and Proximal Polyposis of the Stomach (GAPPS) is a recently described heritable syndrome characterized by isolated gastric polyposis and risk of gastric cancer...

Russell body gastroenteritis has been reported as a reactive inflammatory process in most cases and many of the reports were from the upper gastrointestinal tract, especially the stomach, which may be associated with Helicobacter pylori infection and rarely associated with gastric carcinoma. Russell body containing Mott cells have been rarely seen in Barrett's esophagus and duodenum, and only 2 cases have been reported in colon, including a transplant patient with diarrhea and a rectal tubulovillous adenoma...
