Inverted hyperplastic polyp (IHP) in stomach is a rare benign gastric polypoid lesion, characterized by downward growth of hyperplastic mucosal glands into the submucosal layer. In most previous reported cases, gastric IHP showed mixtures of fundic-type gland, pyloric-type gland, and foveolar-type epithelium. Also, a case of IHP composed of only one type of gland is extremely rare. This report describes a case of a 70-year-old man with gastric IHP, composed only of pyloric-type gland. It was removed completely by endoscopic submucosal dissection, and patient showed no recurrence over 2 years after treatment.

The inverted hyperplastic polyp (IHP) is known as hyperplastic gastric mucosa growth into submucosa and endoscopically presented as sessile or pedunculated submucosa lesion. It occurs in between 3.1% to 20.

Background: Social determinants of health (SDoH) can impact access to healthcare. We sought to assess the association between persistent poverty (PP), race/ethnicity, and opioid access among patients with gastrointestinal cancer near the end-of-life (EOL).
Methods: SEER-Medicare patients with gastric, liver, pancreatic, biliary, colon, and rectal cancer were identified between 2008 and 2016 near EOL, defined as 30 days before death or hospice enrolment.

Gastric mucosa-associated lymphoid tissue (MALT) lymphomas (GML) are non-Hodgkin lymphomas arising from the marginal zone of the lymphoid tissue of the stomach. They are usually induced by chronic infection with ; however, -negative GML is of increasing incidence. The diagnosis of GML is based on histological examination of gastric biopsies, but the role of upper endoscopy is crucial since it is the first step in the diagnostic process and, with currently available novel endoscopic techniques, may even allow an in vivo diagnosis of GML per se.

Inverted hyperplastic polyp (IHP) is a rare disease characterized by the downward growth of proliferative mucosal components into the submucosal layer. It is often misdiagnosed as other submucosal tumors and accurate diagnosis requires pathological examination. Most patients with IHP have no clinical symptoms and some have non-specific symptoms, such as abdominal distension, abdominal pain and even anemia.

Objective To evaluate the gastric microbiome in patients with chronic superficial gastritis (CSG) and intestinal metaplasia (IM) and investigate the influence of () on the gastric microbiome. Methods Gastric mucosa tissue samples were collected from 54 patients with CSG and IM, and the patients were classified into the following four groups based on the state of infection and histology: -negative CSG (=24), -positive CSG (=14), -negative IM (n=11), and -positive IM (=5). The gastric microbiome was analyzed by 16S rRNA gene sequencing.
